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.

    I am experiencing the issue attempting to connect Teams from a Grandstream phone running Android.  I had a similar issue with Teams on a Yealink SIP-T55A but then I noticed it had an alternative option of connecting with a code, from a PC go to https://microsoft.com/devicelogin and then enter the displayed code.  Once the code was entered on the web page, Teams just connected to my account on the phone.

    I would love to know how I can get that version of Teams which would give me the alternative method of connecting using the generated code but I cannot seem to find one like that.

    The T55 version information is:

    Teams Version 1449 / 1.0.94.2020020601

    Perhaps this is something created for Yealink specifically?

    Hey !

    I was also facing same issue and tried many possible solution. But finally I got a solution which worked for me.

    Go to App Managment>>Teams>>Give all permissions to app.

    Then try to login again. It will work.

    Sadly, giving the app permissions to everything didn't solve the issue for me.

    This is what I noticed in the logs:

    X509Util: Failed to validate the certificate chain, error: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

    We use Okta for authentication. So I sent it to our IT department.

    They replaced the certificate.

    That resolved the issue. I was prompted the Okta login instead of that network login message and everything started working.

    Here's their explanation:

    "The way certificate was installed it required the client to download the intermediate cert, which android has problems with sometimes. So they included it, so there is only one download for the certificate."

    Hope this helps.
