We are looking for signalr EXPERT to fix error "Error during WebSocket handshake: Unexpected response code: 400" on aws. and optimize the code.
SignalR working fine with websocket in developer machine but on production (AWS) websocket not working. After that signalr working on Server-Sent event instead of websocket on production machine.
Application is in Asp.Net MVC3, AWS redis, running around 5 instance at a time.
Please only apply if you successfully deployed signalr with websocket app on aws.
