Hi, I'm trying to setup a simple websocket connection from the project game template. Using NWWebSocket 0.5.4 or urlSession.webSocketTask on the client and Vapor on the server.

Haven't been able to connect since macOS ~14-15 with the same Xcode settings.

I can send HTTP routes but the websocket itself does not connect. The closest I've got is connect but then immediate disconnect. I know the websocket works with CLI.

Have plist allowing arbitrary loads and local networking. Also App Sandbox with network boxes checked in Debug mode.

The error I get is:

  Error receiving: Error Domain=NSURLErrorDomain Code=-1011 "There was a bad response from the server." UserInfo={NSErrorFailingURLStringKey=http://localhost:8090/echo, NSErrorFailingURLKey=http://localhost:8090/echo, _NSURLErrorWebSocketHandshakeFailureReasonKey=5, NSLocalizedDescription=There was a bad response from the server.}
Failed to send message: Error Domain=NSURLErrorDomain Code=-1011 "There was a bad response from the server."

Thanks.

Error -1011 is NSURLErrorBadServerResponse, which strongly suggests that the server sent a response that the client didn’t like. I recommend that you use a packet trace to see what’s happening on the ‘wire’.

Hi, please see packet trace
