We are using Blazor App(.net 6.0) with Azure SignalRService. After upgrading Microsoft.Azure.SignalR from 1.25.2 to 1.26.0. having connection issues. After connect client is loosing connection.
To Reproduce
I am able to reproduce it using a new Blazor server app (net6.0) with Microsoft.Azure.SignalR 1.26.0. with Azure SignalR setup
On start it connects to SignalR good, after some time it starts disconnecting. Same setup is working if i use Microsoft.Azure.SignalR 1.25.2. I added full exception details below.
Exceptions (if any)
Exception thrown after first connection
Error while processing messages from k3zYp4BAni-IUqudW3ZmugQ24nYQo02.
