Solved QWebsocketServer + ssl
-
Hi!
I updated the operating system (raspbian) and the previously running wss server is not working. There are no error messages, the socketError or sslError signals are not called. If I try without ssl, it works.
Any idea how to look for a bug?Thanks in advance.

I monitored network traffic to see if it helps:

This is obvious, I do not know the reason. I compiled 5.15.0, but there is the same error. -
I also tried qt 5.11.3 built into the operating system, but the same result.

I got the error, I tried the sslwebsocketserver example, it worked because the code matched mine, I used the key pair in the sample code in my own program, and it worked with it.
How to generate the correct key for qwebsocketserver? -

It looks like those things are contradictory. If you had a running server before updating the OS, you should have created the "correct key" before, right?

Debian strech had a version of openssl of 1.1.0, buster has a version of 1.1.1. I think this is causing the error, but the point is still how to generate a working key pair for Qt? -

There are lots of articles describing how to use OpenSSL to create key pairs, ie. article from Google cloud...

I got the error, I mixed up the filenames, the certificate extension was crt and cert were given back.
