    About 25% of the times when starting a unity build on Android with Gametune to initialize, the following error appears:

    "Curl error 51: Cert verify failed: UNITYTLS_X509VERIFY_FLAG_EXPIRED"

    App built with Unity 2019.2.12f1
    Android 10 (rooted)

    What can I do about this?

    Hi, I've not seen this error before. Does it happen only on the rooted device? What's the device? Are you sure it's related to GameTune and not the IAP/purchase parts?

    I've just got this error now.
    I opened up Hub, and I wasn't logged in.

    When I logged in, my projects loaded as normal.
    But this error shows whenever I play test my project.

    A similar error keeps constantly showing up in my projects:
    Curl error 51: Cert verify failed: UNITYTLS_X509VERIFY_FLAG_UNKNOWN_ERROR
    What does it mean? Can it be fixed?

    I have this problem in the editor as well. I verified the SSL certificate I am trying to connect to, and everything is fine on that end. So it must be an issue with the editor? My colleague does not have the problem with the same version of Unity (2019.2.15f1) on the same platform (Windows) with the same project.

    Also seeing this issue on 2019.2.14
    I'm not doing anything with android, just building for Windows. Game actually builds and runs fine but trying to run play mode in editor immediately crashes the editor

    Curl error 51: Cert verify failed: UNITYTLS_X509VERIFY_FLAG_CN_MISMATCH

    EDIT:
    Verified, same issue on 2019.2.17
    Same issue happens when loading up a completely blank new Unity project
    Downgraded blank project to 2019.2.8 and doesn't present itself

    Unity 2019.3.0f5: UNITYTLS_X509VERIFY_FLAG_EXPIRED when attempting to make a GET request via UnityWebRequest (Not using GameTune, this is a Unity bug)

    Hey, we've just got the same error, when we were making GET request. It appeared that URL we were accessing had expired SSL certificate. we changed https to http and all worked. However, using http might be insecure for your case.
    I hope that helps.

    Hey you guys!
    I got a solution. check out UWR(UnityWebRequest) certificateHandler and assign new CertificateHandler instance .

    CertificateHandler class has virtual method ValidateCertificate()
    Create new class (what you want) and inherit CertificateHandler class. ValidateCertificate method implement override that should be return value is true.
    CertificateHandler objecct assign to UnityWebRequest.cerificateHander.
    It will be works fine.

    We've done some testing and found that this issue is resolved in 2019.3.1. Our issue is related to the DNS resolver on our PFSense router. The issue is consistent across all operating systems from 2019.2.9 through 2019.3.0

    The same error in Mac OS Catalina when I fixed the issue with Network Link Conditioner (I had an old version of this tool installed). After these steps and the successful launch of the updated version of Network Link Conditioner (for Xcode 11.4) and the on/off option "Very Bad Network" I found three UNITYTLS_X509VERIFY_FLAG_EXPIRED errors each time when I start the Unity editor.

    Guys, a temporary solution if your unity project doesn't require internet features.
    Switch off your internet connection to your PC.

    Use your mobile for internet usage.

    Same here.

    Everything was working fine until 30 minutes ago - now Unity crashes on pressing Play since this error appeared.

    Using version 2018.4.14f1

    I'm guessing one of Unity's own SSL certificates may have expired?

    *Edit - I'm getting the same issue on version 2018.4.19f1

    I guess unity is doing curl requests to something with a very recenltly expired certificate...
    But why would unity need to curl anything ?

    I received the same error this morning for the first time. All I did is open my project. I'm guessing the Editor or package manager is querying for updated versions? It throws the same error at fast intervals at first (every second), then slows down to every minute, then every 5 minutes.

    (see attached)

    Editor and project worked fine last night. This morning I can't even hit play without it crashing. Maybe a certificate expired on their end.

    Found this in the logs:

    Code (CSharp):
    1. Subscribe to USB device events
    2. EditorUpdateCheck: Response {"latestversionstring":"2018.4.22f1 (3362ffbb7aa1)","latestversion":99999,"latestversionmessage":"A new LTS version of Unity is available. Please update to the latest released version at your convenience. Release notes available on the download site.","updateurl":"https://unity3d.com/unity/qa/lts-releases","updateinterval":3600} updateurl = https://unity3d.com/unity/qa/lts-releases interval = 3600
    3. Hub Web Socket connection default:(null):reason:29
    4. Hub Web Socket HTTP protocol init
    5. Refreshing native plugins compatible for Editor in 17.51 ms, found 2 plugins.
    6. Curl error 51: Cert verify failed: UNITYTLS_X509VERIFY_FLAG_EXPIRED

    I recommend everybody to report the issue throught the bug report form in the editor:

    https://unity3d.com/unity/qa/bug-reporting

    It should be a super quick fix for Unity, the more reports flood in, the earlier they will take note.
