SignalR doesn't work in this case:
-.NET core Web API hosted on AWS Lambda that configured with SignalR.
-Vue Web site hosted on S3 bucket also configured with SignalR.
Both can't connect on AWS, but they work fine locally on my machine.
I tried to specify the transport type explicitly ( SSE , Long polling)
but in vain.
Error messages I got until now, stuff like the following :
<b>
"Server returned handshake error: Handshake was canceled" <br/>
"Error: Connection disconnected with error 'Error: Server returned handshake error: Handshake was canceled.'"<br/>
</b>
Would it help trying to deploy to Azure instead of AWS ? as Azure SignalR service might help more than AWS ?
