Hi, @Satva Solutions
It's hard to provide userful information for your case. I suggest you could gather more diagnostics from your application to help troubleshoot issues. The details you could check this article Logging and diagnostics in ASP.NET Core SignalR.
In the default configuration, SignalR logs very little information, but this can configured. See the documentation on ASP.NET Core logging for details on configuring ASP.NET Core logging.
