Error code - caa30194

There's a more permanent way to sign in to Microsoft Teams. If you're having trouble completing the process, talk to your IT admin"

Our company has been using Teams  for a while, it works very well for me until today. I can't sign in Teams desktop in my computer after I upgraded my OS from Win7 to Win10. But the funny part is that Teams web and Teams in my Phone(android)  are still working very well. The desktop Teams feedbacks with error code: 0xCAA30194, which is attached below. Can anyone help with it? Thanks in advance.

    Alessandro,

    I found that enabling TLS 1.0 / 1.1 and 1.2 in Internet Options has fixed this for me. 

    I turned off 1.0 and 1.1 for something else a while ago. Turns out you kind of need these onfor Microsoft Teams.

    I hope this works for you man!

    Kind Regards,

    Jeff

    Hi,

    I tried this, so now Teams doesn't work.

    I cleared the cache, deleted JSON files, restart application and nothing happen.

    Do you have some another advice, please?

    Hi,

    I have had this problem, too. After following all solutions suggested in this post, I uninstalled and reinstalled the desktop version for Win10 of Teams. That solved the problem.

    Same situation. I have tried all the "workarounds" in stated in the replies, but none worked for me. 

    How do I generate the error log files for you?
