Dear @Matej Balaban,

First of all, I want to begin by sincerely apologizing for the frustration and inconvenience this issue has caused you.

The error message you're seeing on Android particularly with the specifics like "Error Something went wrong. [5nlhg]" and the accompanying error codes (Correlation ID, Error Code, DPTI, etc.) is a fairly generic one. However, its likely points to an issue on the server-side or a misconfiguration in the user's account settings.

I understand how frustrating it can be when errors like this disrupt your ability to use Teams, and I appreciate your patience while we work through this together. This error code and tag don't appear widely documented, which may point to an app-specific issue, or something related to your account, device, or network settings.

To better understand and investigate your issue, may I get some more detailed information from your side:

1. What version of the Microsoft Teams application are you using on your mobile device? Have you checked for Teams updates?
2. What Android device model and version are you using?
3. If possible, please take a screenshot of the issue you're experiencing so I can better assist you.

In the meantime, please try some steps below and check if it helps:

1.Microsoft Teams update to the latest version. Version update history for Teams app deployments - Office release notes | Microsoft Learn 

2.Remove the account completely from Android: If clearing data didn’t help, try removing and re-adding your email account:

• Go to settings > Accounts > Remove school/work account > Reboot phone > Reinstall Microsoft Teams > Sign in only after reinstall (don’t let Android auto-add the account)

3.Force close and reopen Teams

• Go to Settings > Apps & notifications > Teams.
• Tap Force Stop and confirm.
• Reopen the Teams app.

4.Check app permissions

Ensure that Teams android has all necessary permissions:

• Go to Settings > Apps & notifications > Teams > Permissions.
• Make sure all relevant permissions are granted.

5.Check for Server-Side Issues

The correlation ID, timestamp, and error code are often used by Microsoft support to trace errors in the backend, which could mean there might be a problem on the server side, like an outage or a configuration problem with the user's Office 365 account or Microsoft Exchange. You can:

• Check Microsoft Service Health Dashboard to see if there's a known outage or service issue affecting Teams services.
• Alternatively, you can use your admin access in the Microsoft 365 Admin Center to check for service incidents.

Additionally, you may review the helpful post below regarding a similar issue and try the steps mentioned there to determine whether any of them work in your case: Tried to login but getting the error

If these steps don’t work, it might be necessary to escalate this issue further with the correlation ID and timestamp, as they can use this information to look deeper into server-side issues. I sincerely recommend you try to create a support ticket from Microsoft 365 Admin Center>Support>New Service Request. You can raise support ticket from: https://admin.microsoft.com/Adminportal/Home?#/support/requests

The support team over there has higher permission than us to investigate the issue from background, they have more resource and correct escalation channel in handling this kind of issues. This would be a more efficient way in handling the case for you. 

For reference:  Get support | Microsoft Docs     

Please understand that our initial response may not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.

Appreciate your patience and understanding and thank you for your time and cooperation. Have a great day!
