Bug Curl errors

Recently I keep getting the following error but remote config still working properly but I think it's still better to solve the errors.

Curl error 28: Failed to connect to cdp.cloud.unity3d.com port 443: Connection timed out
Curl error 6: Could not resolve host: cdp.cloud.unity3d.com

 

@Unity_SebT I'm using remote config 3.0.0-pre.8. Seems like during fetch the values and after fetch the values still keep logging error few times. I guess timing of error log is quite random.

 

Just let u know the error I didn't see those errors at editor. Currently I see it at Android build and Windows build. Seems like it will only happen at real build. Btw for the "6) Make a copy of the folders you find that have remote-config in the folder names" I not really understand. Is that u want me copy remote config to Package folder to make it become local package?

 

Ya. I also using latest "com.unity.remote-config-runtime": "3.0.0-pre.18".

Unity 2020.3.25

 

@Unity_SebT From what I observe, I believe remote config is not cater for not really stable network environment that will keep fluctuating or maybe remote config is not stable for certain countries like SEA countries I dunno. I give other people to test the real game and they also have the same curl error so I think it's not Router/ Adblockers / firewalls issue. Maybe u can try to test Malaysia network.

Btw seems like new Remote config 3.0.0pre.9 release is not working properly. ConfigManager.FetchCompleted event no longer fire anymore.

 

@optimise When did this start happening? Does it occur in your testing with a newer Android device? Does it work in the Editor?

 

@JeffDUnity3D I believe it can reproduce with any Android device regardless of version. Actually even at Editor u also can reproduce similar error.

 

I am not able to reproduce here as you describe, but I do believe you. And you've turned of any firewall and ad blockers including in your router? Can you try using a different network, like a phone hot spot?

 

Alright.

Android phone tested with wifi.

Tested by another person with phone hot spot and with different phone.

I also get one interesting error but I forget whether it's at Android build or editor but I believe it's at Android build.

As mentioned, I believe you but I'm not able to reproduce. Does it still operate correctly for you and these are just warnings?

 

Not really I guess. Although it seems working fine for most of the time but sometimes it will not properly though. When it doesn't work properly it stuck at forever or takes very long time to get the result.

 

Please don't guess! Does it work in your testing? What result are you referring to?

 

Maybe let me do more testing and observe the error message when it doesn't work properly. Actually I integrated remote config long time ago and testing the game almost every week.

 

In the words of Yoda, "There is no maybe, there is test or no test"

 

@JeffDUnity3D I captured some logcat for u went it doesn't work properly. For this it suddenly become fetching config from production environment instead of develop environment.

@optimise Got it! Can you provide steps to reproduce, when does this occur. What is different during this test? Please share your code where you set your environmentID for Remote Config.

 

Honestly I just launch my game app and let the remote config load itself all the time. I dun really have any special steps to reproduce. Below are the code snippet. Currently I'm using Remote Config 3.0.0-pre.8 since 3.0.0-pre.9 is buggy and not working.

Spoiler

bool isSignInAnonymouslyAsync = false;

try
{
var environmentID ="develop";
var options = new InitializationOptions().SetEnvironmentName(environmentID);

// Initialize handlers for unity game services
await UnityServices.InitializeAsync(options);

// Remote config requires authentication for managing environment information
if (!AuthenticationService.Instance.IsSignedIn)
{
await AuthenticationService.Instance.SignInAnonymouslyAsync();
isSignInAnonymouslyAsync = true;
}
}
catch (Exception exception)
{
// An error occurred during initialization.
Debug.Log($"{exception}");
}

ConfigManager.FetchCompleted += ConfigManager_FetchCompleted;
ConfigManager.FetchConfigs(new userAttributes(), new appAttributes());

if (isSignInAnonymously)
{
AuthenticationService.Instance.SignOut();
isSignInAnonymously = false;
}

Spoiler

void ConfigManager_FetchCompleted(ConfigResponse configResponse)
{
switch (configResponse.requestOrigin)
{
case ConfigOrigin.Default:
//Debug.Log("Default values will be returned");
break;

case ConfigOrigin.Cached:
//Debug.Log("Cached values loaded");
break;

case ConfigOrigin.Remote:
//Debug.Log("Remote Values changed");
Debug.Log("ConfigManager.appConfig fetched: " + ConfigManager.appConfig.config);
break;
}

 

Your code looks correct. So randomly it sometimes works and others not, with no code or network changes? How often? You mention "all the time", can you be more specific? One minute it works, and the next not? And your environmentID is hard-coded? I'm not doubting your claims, we are just trying to find exact steps to reproduce here.

 

Ya. All the time I mean with no code or network changes. I just test my game as usual. It works most of time but when it doesn't work then it will become fetch wrong data from another environment or just stuck there forever and never fetch data. Actually my environmentID is not hardcoded but I can confirm it's deterministic.

 

@JeffDUnity3D Btw one feedback for ConfigManager.FetchCompleted action. Can u modify internal code logic to make ConfigManager.FetchCompleted action call on main thread again? The previous remote config is working properly until recent version. The current remote config internal implementation breaks my project and I use super hacky to check it every single frame until ConfigManager.FetchCompleted has response.

 

One issue per thread please, best to open a separate thread

 

Got it. Agreed it sounds like an issue at our end, from your description. A Charles Proxy network capture would really help, but it might be hard to grab one due to the random nature of the issue https://support.unity.com/hc/en-us/articles/115002917683-Using-Charles-Proxy-with-Unity
