Azure SignalR Service is not connected yet, please try again later

Question

I am using Azure SignalR on Asp.Net Core 3.1, I receive SignalR message from azure service bus on API side (Back-End) and want to send the message to Angular client side (Front-End) as notification using azure SignalR. But getting this error

Answer 1

I got this error when using aad connection with a service principal. I forgot to grant SignalR Service Owner role to the service principal which caused this error.

After providing the correct role and waiting a bit, it started working.
