It turned out that nginx was returning 301 while trying to redirect from http to https (it had nothing to do with the endpoint itself thankfully).

I changed my websocket URL to "wss://" + url and that seemed to resolve the issue for me.

For future readers, if you are still experiencing errors with a Secure WebSocket you may want to adjust the SSL configuration of the QWebSocket.

QSslConfiguration sslConfig; sslConfig.setProtocol(whateverProtocolYouDesire); // Set additional properties of sslConfig here... socket->setSslConfiguration(sslConfig);

The code answers there all implement sending Qt error messages within an application to a file. Perfectly useful in itself, but nothing to do with the topic title here of "How to redirect stdout & stderr to a file in a Qt console App (QCoreApplication)".

I did as you suggested https://bugreports.qt.io/browse/QTBUG-63313 . Hope the bug report is properly documented

If it needs a named pipe then you should ask the author.

AFAIK, you should be able to connect to a named pipe using QLocalSocket
