Discussion on: Protect Your SignalR Service Based Real-time Application with Application Gateway

thanks will look into that , While I following this article during the configuration of app gateway, on setting up the probe i got the issue like below

Unhealthy logs

Cannot connect to backend server. Check whether any NSG/UDR/Firewall is blocking access to the server. Check if application is running on correct port. To learn more visit - aka.ms/servernotreachable.

Any idea how to fix it ? Without fixing this i cannot move forward

P.S All the other configuration in app gateway i can able to complete as per the blog.

It seems that this SignalR instance is not accessible in your scenario. Would you please try these potential actions to narrow down this issue?

1. Which region are you using right now? Would you please share the resource ID of the SignalR instance with me for further investigation?
2. Would you please grant the public permission of this SignalR instance and test whether it is in good shape?
3. Could you please enable the diagnostic logs to learn what happens with the health probe?
