PurchaseFailureReason: Unknown

Hi there,

I have a mobile game that's live both on Android and iOS. I last updated it at the end of January and in the live version the shop works great. I only have simple consumable products like gems and coins, nothing special. Since then I've worked on updating game mechanics that have nothing to do with the shop so nothing was touched there. I did however update the IAP to the latest version 1.18. I was getting ready to push a new update earlier this week when I noticed that the shop process no longer works, it gives me an error. I've attached 2 log files from which I've stripped any information that might be sensitive to the game. The log.txt file has the game running on my iphone and using my WiFI while log_mobile_network.txt uses the cellphone network. Through the same networks, if I delete my update and just re-download the game from the app store, the shop works just fine. I'd also like to mention that the product IDs are the same on both stores and like I previously mentioned, I haven't made any changes to the shop code which is based on your tutorial from https://unity3d.com/learn/tutorials/topics/ads-analytics/integrating-unity-iap-your-game .

I also get while running the game in the editor the message "Failed to fetch IAP catalog due to unexpected http status code, attempting to use cache" if that counts for anything.

Unfortunately I'm not really sure what to do or what to even search for to try and find a solution myself. I would really appreciate any help, thank you!

 

Not sure if this helps, but I tried pushing the same update on an android device and I'm getting "BuyProductID FAIL. Not initialized." However, in my code I do have in my Start() if (m_StoreController == null) { InitializePurchasing(); } and I added a Debug.Log right before it just to make sure it goes through and it does. My InitializePurchasing() is very similar to the one from https://unity3d.com/learn/tutorials/topics/ads-analytics/integrating-unity-iap-your-game .

 

I saw btw in the other posts the "1001 - The connection timed out." error. The problem with that however is that if it's a connection issue, shouldn't I be experiencing the same problem with the version of the game that's currently on the store? How come that one works? Thanks!

 

Hi, i face the same right now. Always failed purchase due to unknown reason. Is that itune store timeout?

 

I'm also getting it on Android so I think it's something else...

 

Here's a stripped down version of my shop code. I removed all the UI/database code and left just the IAP stuff:

And attached you can see a screenshot showing the product IDs from my Apple Store and Google Store. They're identical and correctly added inside the code.

Also the game is called TomeOfHeroes, if you need to install the live version you can find the links at www.tomeofheroes.com

Let me know if there's any other information that I can provide and thanks in advance for any help!

 

The 1001 error is a store timeout. Can you provide your Android logs too?

 

Hey Jeff, unfortunately I'm not able to provide Android logs at the moment. So my understanding is that the 1001 error means that there's something wrong with the connection from my device and to the Apple Store correct? However, if that's the case, why doesn't the live version of the app provide the same error and only the new update? If it's a connection issue, shouldn't both return the same 1001 timeout considering I'm running them from the same device and over the same connection?

 

@stefanplc Agreed on your observations. I'm checking with the IAP team whether there were any changes to the timeout settings in the latest version, and will keep you updated.

 

Thank you very much Jeff, appreciate your help!

 

Here's the Android log that I stripped down a bit of any info that may be sensitive to the app. Thanks!

 

@stefanplc It looks like IAP initialization is failing, but I'm not seeing it called anywhere. Where in your code are you initializing IAP? Should be in Start()

 

Isn't it the call at line 29? InitializePurchasing(); The function is right bellow it starting with line 33.

 

Yes, but I'm not seeing the initialization in the logs. Perhaps you stripped it out? To capture logs on Android, I generally use "adb logcat | grep -i unity". On Windows, I use findstr instead of grep.

 

Here's a new full log from Android Studio. Let me know if this helps, thanks!

 

And here's a full iOS log of the same process. I open the game, open the shop window and press the buy button.

 

Please use grep/findstr as requested, it will save time to isolate any Unity errors. Please provide line numbers of errors that you see, I will confirm and look for other possible issues. Thank you for understanding.

 

Hey Jeff, unfortunately I don't know what grep/findstr are, but I did google them and looking at what you wrote, I believe you would just like me to list out the errors I'm seeing in the logs regarding the IAP?

Is this what you needed me to do?
Thanks!

 

I just looked at the tutorial article again and compared it with my shop script and as expected they're almost identical, I just have a few extra lines of code for UI animations. I'm going to try and update from Unity 2017.2.0p1 to 2017.4.1 and see if that does anything. I'll keep you updated, thanks!

 

I updated to 2017.4.1 and re-imported the IAP but still nothing, same errors.

 

I am experiencing the same problem. I had a a live build with IAP functioning properly. Everything seemed ok in the TestFlight environment and the live version was ok (although I was getting a lot of PurchaseFailure.UserCancelled errors). I went to work on other things, and updated to IAP 1.18, and now the IAP system doesn't work.

When you hit the purchase button, the app just sits there, for a very long time (about 3-4 minutes), and eventually returns a PurchaseFailure.unknown error. I got some log reports from XCode, and they do appear to have the 1001 timeout error. Specifically, the CPU was caught waking 45001 times over 215 seconds, violating the CPU wakes limit.

I'm attaching a screenshot of the log files here. On another note, working with the IAP system has been endlessly frustrating. We have been struggling with it for 6 months, and every update causes huge problems. The feedback from log reports is usually useless (PurchaseFailure.unknown!) and the documentation is still very poor 6 months in. The Unity team really needs to do something about this as this code base is not up to Unity standards, which I have found otherwise to be very high. Moreover, as the IAP system is absolutely critical to monetizing games, and can be a huge source of negative user feedback when it goes wrong, this should be a top priority.

 

May I please get a list of all the files that get updated when I update the IAP? I know the folders UityChannel and UnityPurchasing do, but I think there may be a couple of other files too. I tried going back to Unity 1.15 by downloading those 2 folders from an older GitHub backup and it's still not working so I'm wondering if I missed some.

Or is there a better way to downgrade to a previous version of the IAP?

Thanks!

 

Supporting downgrading is a feature we are working on. In the meantime, many developers take advantage of a source control system to perform downgrades. I do understand your frustration. All the necessary files are contained in Assets/Plugins/UnityPurchasing and Assets/Plugins/UnityChannel. What is the error that you are seeing when trying to move to the earlier release? This post may help: https://forum.unity.com/threads/iap-troubleshooting-remove-and-reinstall-unity-iap.511747/

 

For IAP 1.16 and 1.17, please see this post https://forum.unity.com/threads/unity-iap-versions-1-16-and-1-17-available-for-download.527432/

 

Hey guys,
Thank you so much for the fast replies! Here's an update from my end: I spent all day yesterday trying to roll back via github in increments of every 1 month and then I pushed those builds on my test phones for both Android and iOS to see if the shop worked since it appears to do so on the live version. This took a while as each roll back required roughly 30 minutes of Unity re-importing the files. Eventually I got to December where I was using IAP 1.15 and even though it didn't work still, on Android I was now getting a pop-up message from Google Play that the product wasn't available for purchase. Before with 1.18 it wasn't doing anything at all. On iOS, with 1.18 the iPhone wouldn't do anything for a few minutes and then it would give me the unknown error with 1.15 it gave me the error right away.

I did some more research and the errors of "No App Receipt found" in iOS (lines 419 and 421) and product not available for purchase on Adroid might actually be from the store and the only way to fix them is to push the update live.

So next I took the 2 folders from the Plugin folder titled UityChannel and UnityPurchasing from my December version and I placed them in my latest update. It took a couple of Unity restarts but eventually I got it to give me the same error from December on this latest build. I then used the links with the IAP packages that you guys provided and upgraded to 1.16 and that seemed to provide the same errors too. I didn't get a chance to try 1.17 yet but I will do that shortly. I should also mentioned that I first tried this with Unity 2017.4 and I didn't get the same results. I had to do it with Unity 2017.2.0p1 which is what I've been using for the past few months.

My plan is to push my app on both stores with either IAP 1.16 or 1.17 and see how that goes. Luckily I don't have a lot of users playing my game as I would like to add a bit more content before I start marketing so it shouldn't be that big of a deal if it ends up not working.

I'll let you know how things go,
Thanks!

 

Hey guys,

My submission to the iOS app store just got approved and should be live on all stores in a few hours. I ended up going with IAP 1.17. I assume that in the end the errors were as I explained that the purchase process doesn't work unless the app is downloaded from the store. Last time I worked on the shop part of my game, I was able to just push updates directly to my devices from my computer and test the shop that way but I guess that's no longer the case.

I didn't actually get to test that everything's working fine, but I don't think Apple would have approved my update if there were any issues. If I do encounter any problems I'll let you guys know. Thank you very much for all of your help and assistance!

 

The stores actually updated a lot faster than expected and I can confirm the shop works great on both Android and iOS . Thanks again!

 

Hi, I am facing the same issue with iOS ONLY. Android is completely working fine.

It able to find products and get those price, but always filed OnPurchaseFailed with Unknown reason once clicked the item:

IAPButton.OnPurchaseFailed(Product UnityEngine.Purchasing.Product, PurchaseFailureReason Unknown)

Unity 2018.2.8f1
Unity IAP: 2.0.3

Anyone could help ?

 

Hi, I get an error "PurchaseFailureReason: Unknown" after I bought a subscription with a trial period, then I canceled it until the trial period ended, and then I try to restore my purchases. In the AppStore settings on iPhone I do not have a subscription, but the trial period is still valid. But in fact, I have a error in the game and there is no possibility to use a subscription until the end of the trial period.
Unity 2018.3.4f1.

 

When and how are you receiving the error. Please provide specific steps to reproduce. And please check your grammar "canceled it until the trial period ended" is a bit confusing.

 

Sorry for bad english.
My steps:
1. Run game.
2. Hit "Buy subscription" button (for 3 month with 3 free day period).
3. Entered account password.
4. Got successful purchase window from AppStore.
5. Return to the game
6. Checked subscription activated.
7. Exit game, delete game.
8. Go to Settings > iTunes & App Store, tap my Apple ID at the top of the screen, tap View Apple ID, entered password, tap Subscriptions, tap Cancel Subscription. Subscription is canceled, but there is a text "Expires 28 Feb 2019".
9. Download again my game from Appstore and run.
10. Hit "Restore Purchases" button.
11. Got error in my special debug log window (opened after 3 seconds touching in special place on the screen).

 

Got it! You mentioned the Package Manager version, what is the IAP Asset version? Go to Window/Unity IAP/IAP Updates and the version will be listed at the top of the dialog. The latest is 1.20.1. We are hoping to improve the disconnected scenario in upcoming releases. In the meantime, you likely don't want to give the user the product when you encounter this error.

 

But yesterday I updated both components of Unity IAP and now have this:


After that I uploaded new build on AppStore, but it still is pending of review.

 

Did you test and confirm behavior before uploading a new build? I'm not clear why you uploaded a new version? You would want to test in TestFlight first, or on your own device before publishing a new release.

 

In Sandbox I can't test this scenario because I can't cancel my subscription. The rest of the functionality works well. In addition, the free period expires very quickly in Sandbox. And since this scenario has a small chance I decided to test on the released game.

 

Yes, you would need to create a new subscription, or use a new user account

 

No, that's not the problem. In the Sandbox there is no functionality at all to cancel the subscription. It doesn't matter whether a new user or not.

 

Yes it does. A new user would be able to subscribe. Cancelling a subscription is on a per-user basis. Other users can still purchase.

 

I had also this error, in particular "getSkuDetails() failed: 6:Error", and in my case it was a misconfiguration in my device: I had three different Google accounts and only one of them had testing permissions, so I basically removed all but that one from the device.

 

We have determined one cause of the 6:error is changing the users password on Google Play on the web, but not (yet) on an unlocked (no screen lock in place) device

 

I have a similar problem. I'm using IAP button and when i click buy product its giving me purchase
failed, reason unknown error. I'm using Unity 2019.2.13f and last version of iap. Any help?. Thanks.

 

Please provide more information, and provide the device logs https://forum.unity.com/threads/how-to-capturing-device-logs-on-android.528680/

 

I am having issue with the live version on iOS, the in-app purchases are working fine on Sandbox environment but the live version fails on OnInitializeFailed. On Android everything is working fine.

All the tax and banking information is added and in-app purchases are also Approved but still somehow they are not working only on live version.

 

Please provide the device logs from XCode

 

Thanks for your response but the in-app purchases started working automatically after a while. I don't know how but I guess there was a delay from Apple regarding in-app purchases.

 

Hello,

I am facing a similar issue on an app currently in production on a mobile device.
Purchases work fine on all iOS and Android devices except for one device: Samsung S7.

For that device, the IStoreListener.OnPurchaseFailed method is called with a PurchaseFailureReason of Unknown.Here is an excerpt from our logs:
The first log entry is emitted by Unity code the second is by our OnPurchaseFailed method implementation from the IStoreListener interface:

Code (CSharp):

1. -[Log] onPurchaseFailedEvent({0}): CardPack_SixFlags
2. UnityEngine.Purchasing.Extension.UnityUtil:Update()
3.  
4. -[Error] IAP InAppPurchaseManager -- OnPurchaseFailed -- productID: CardPack_SixFlags, reason: Unknown
5. Nvizzio.RCTM.IAP.UnityIAPManager:OnPurchaseFailed(Product, PurchaseFailureReason)
6. UnityEngine.Purchasing.Extension.UnityUtil:Update()

As mentioned above, the same code is executed on all devices but failures occur only for this particular device.
The Unity version used is 2018.4.20f1How can we:

• obtain more details as to what is causing the issue?
• fix/workaround the problem?

Thanks in advance,
Max

 

I have a Galaxy S7 Edge and IAP works great on it. Are you testing with the latest IAP version 2.0.0? So you have that specific device and are able to reproduce?
