Please enable the WebSocket feature in your Azure server.

hi

Let me check it on the azure website.

And share your logs.txt again. Thanks.

hi

You better download the source code of the Chat module to customize your new feature.

There are some services in the Signalr module.

hi

Please add the MyBlazorServerLookupApiRequestService to your blazor project and try again. The error logs will show the reason.

After the above test, you can add RemoteServices to your appsettins.json

  "RemoteServices": {
    "Default": {
      "BaseUrl": "https://your-real-url-dev.azurewebsites.net/"
    }
  },

Thanks.
