    I'm looking forward to the .NET Scripting Runtime upgrade, and am seeing Websocket TLS errors coming from the Firebase C# Plugin. I'm not sure if this is ultimately a fix that will need to go into the firebase C# api, or unity.

    Can you submit a bug report with this project? This certificate errors are notorious finicky, so I would like to be able to investigate it here.

    @JoshPeterson I submitted a report to Unity + Firebase. The Firebase team says they are unable to reproduce, I'm not 100% sure the support staff are familiar with the steps involved to run Unity with the newer runtime so I made a screen-recording of the issue & git repo.

    Thanks! We will continue to investigate on our side as well. If you hear from them that it is corrected, please reply via the bug report so that we will be aware. Thanks!

    This error comes from not web-socket client library. The mono implementations for a lot of these things do not implement the TLS handshake correctly.... and are buggy in general. There are a few solutions for this problem. If you search Xamarin bugzilla you will see a few people crying over this bug (including myself).

    1. Change the websocket transport. All of them suck.
    2. Disable SSL / TLS
    3. Rewrite mono to correctly support SSL.
    4. Use a native websocket and use a bridge to bring it into unity.
    The last step completely side steps mono, and thus works the best. I would contact firebase and have them fix the issue.

    While we don't have a good solution for TLS with Mono at the moment, it is an active area of development. So longer-term, I would expect better support for this kind of thing in future Unity releases.

    With Unity 2017.2.0b8 + .NET4.6 + Firebase Unity SDK 4.0.3 ( https://firebase.google.com/support/release-notes/unity ) there is some improvement, the Websocker error is not thrown, and instead a workaround log is output to the console.

    But FirebaseDatabase doesn't seem to return either an err or result following the Firebase example code ( https://firebase.google.com/docs/database/unity/retrieve-data#read_data_once ).

    Using workaround for .NET 4.6 certificate bug.
    UnityEngine.Debug:Log(Object)
    Firebase.FirebaseHandler:LogMessage(LogLevel, String)
    Firebase.Unity.UnityLoggingService:LogMessage(LogLevel, String)
    Firebase.Unity.InstallRootCerts:.ctor()
    Firebase.Unity.InstallRootCerts:.cctor()
    Firebase.Unity.UnityPlatformServices:Install(GameObject)
    Firebase.FirebaseHandler:<Create>m__0()
    Firebase.FirebaseApp:TranslateDllNotFoundException(Action)
    Firebase.FirebaseHandler:Create()
    Firebase.FirebaseApp:get_DefaultInstance()

    Is this specific to iOS / Android? Or is there support for standalone (Windows / OS X) now?

    I have the same issue for Android with Unity 2017.2.0 and 3.0
    The solution for me was in logging out from Unity account and checking "Work offline". After this, my build was successful locally. On Unity Cloud I don't have this issue

    This particular issue should be fixed in 2018.1 betas. It's unclear if this will be fixed in 2017.x series.

    New TLS support infrastructure is planned for all of Unity including the .NET/Mono APIs for 2018.2.

    Wait did you mean the firebase problem or the one I linked to specifically? If you meant my problem would you point me in the right direction for which beta version? Latest beta seems to not solve it.

    I thought that all of the issues in this thread were corrected. Can you submit a new bug report?

    The problem was present only on physical device. I fixed that by re-importing all sdk, force resolving dependencies, rebuilding the project, changing scripting run-time version to .NET 3.5, and API compatibility level to .NET 2.0. If I will experience the issue again I will submit bug report.

    This problem goes on,
    I am using Unity2018.2.6 + Firebase 5.2 in Mac
    The procedure to reduce this is the same as ItsLeeOwen reported in Jun 13, 2017.

    I found the problem, it is the firewall.
    I changed the network to a private one instead of the one for company.
    Then it worked.

    I was getting a similar error that led me here, so I'll leave my solution in case anyone else runs into the same issue

    Error message

    
[Error] WebSocket: ws_0 - IOException during handshake
    
System.IO.IOException: The authentication or decryption has failed. ---> System.IO.IOException: Error while sending TLS Alert (Fatal:InternalError): System.IO.IOException: The authentication or decryption has failed. ---> System.ObjectDisposedException: Cannot access a disposed object.
    
Object name: 'System.Net.Sockets.NetworkStream'.
    
  at System.Net.Sockets.NetworkStream.BeginRead (...


    Solution (required two changes)
    1. Generate and setup a p12 file for firebase from google cloud services, as stated in the docs.
    2. 
    FirebaseDatabase.GetInstance
    must be called AFTER logging in via 
    FirebaseAuth
    , the 

    
CheckAndFixDependenciesAsync().ContinueWith
    callback is not good enough.
