Teams App Not working on Android Devices

Has this issue been resolved? What is the fix? A few users are having this problem and the company has given us all the access that is needed. It worked for 2 months until last Thursday now we get this new message. Tried everything from clearing cache, uninstalling, no ms auth app is installed, tried with  Company Portal and without and continue with issue.

Teams App Not working on Android Devices

So recently our organization decided to use Microsoft Teams for our communication. And It is working fine on Web and iPhone But no one is able to login on Android Device. Whenever we try to login on Android Device using Team App, we get this error.

There was a problem with the network. Try signing in again

I have logged in using same credentials on iOS and Web and It worked but same credentials are not working on Android.

Please guide me, how to fix this issue as it is very urgent for us.

 It comes up with there was network error signing you in or

As it turns out our issue was between our reverse proxy and with later versions of Android being stricter on requirements by the looks of things.

Look for a "Require SNI hostname" setting in any load balancers or reverse proxies to your Federation services and try adjusting that if necessary. This was the fix to our issue.
