Please confirm that your connection string is correct. Additionally, did the issue only occur in the Azure Container Apps or it could be reproduced locally?

Please confirm that your connection string is correct.

yes, can confirm. I am using primary connection string. Also it does work intermittently.

It seems to work locally and I am not seeing the "Failed to connect to" errors in my local logs.

This doc might help: Troubleshooting methods. You could also send your SignalR resource ID to zityang@microsoft.com for us to check backend log for you.

thank you, I will check out the troubleshooting methods. I will email the resource id to you.

From the logs in the back end, you should be using AAD auth instead of access key. Error code "403" means the app doesn't have the correct role. The strange thing was that 403 only occurred on one IP address. Please confirm all your app instances have the correct role. Hope these information helps you.
