@Paul_By - We are not able to repro the issue, it's working fine from our end.
we tried with the below sample-
https://github.com/OfficeDev/Microsoft-Teams-Samples/tree/main/samples/bot-teams-authentication/csha...
Microsoft Teams Version 1.5.00.34469 (64-bit)

If the session has expired due to any intermittent connectivity issues or interruptions, a “500 " appears.

Could you please share the console error, so that we can investigate from our end?

Thank you. We will check access to our Login form & token.boteframework.com (Azure side).
