Logs

This problem has been intermittently affecting several office developers at Microsoft. The broker authentication is failing for some reason. However, we found a temporary solution by switching to a non-broker authentication mode in GCM by setting credential.msauthUseBroker flag to false in the git config file. Redacted logs are attached for further analysis.

Looks like it's a bug with MSAL broker flow and they just seemed to have fixed it AzureAD/microsoft-authentication-library-for-dotnet#4696 today. Once GCM consumes the latest MSAL, this issue would be fixed.

MSAL fixed the bug and released a new version 4.61.1.
