Hello dear MS-community,

since last week there's an issue with SignalR without any changes prior to that. It seems that the client doesn't receive the messages from SignalR on the web application.
Inside the SignalR Diagnostic Logs there's the following warning which unfortunately doesn't give enough information to fully debug this issue:

Note: The caller IP address inside the image is from our Backend App-Service.

Best regards and thanks in advance.

    Hi @enes.uenalan , I reached out to the product group with regards to the issue reported in Getting "500 - InternalServerError" when using REST API for groups (POST). It's been identified as a regression bug and will be addressed in an upcoming hotfix. There's an opportunity to have the fix directly applied and see if it resolves your underlying issue, or just wait until the hotfix is rolled out.
