I'm using Azure SignalR Service and am getting the error message below:

WebSocketTransport.js:85 WebSocket connection to 'wss://mysignalrservice.service.signalr.net/client/?
hub=contestchange&id=my_id&access_token=my_token' failed: Error in connection establishment: net::ERR_CERT_AUTHORITY_INVALID

Chrome Console Error

Any ideas on how I might resolve this?

It turns out this was due to setting the SignalR feature flag Service Mode to Serverless. Once I set it back to Classic it started working as expected.
