SSL error: unexpected eof while reading (in ) on browser refresh of TLS crossbar connection #2047

Closed antonymott closed 1 year ago

Browser (autobahn.js client) securely connects and generally functions OK over TLS connection, except on each browser refresh (chrome on debian 10):

SSL error: unexpected eof while reading (in )

Perhaps it's related to another SSL error I was able to reproduce over here if I try to add a container component to the config: https://github.com/pyca/cryptography/issues/7488

I did some tests to see if I can help narrow down the problem. I tried to securely connect a python client, same error. If I had to guess, although the problem appears as a crossbar router problem, it's probably in the Twisted parts of Crossbar, in the way in which openssl is used by Twisted.

The TLS for web works fine, in contrast to wss, and https:// passed all external TLS tests. So the problem seems narrowly wss.

My workaround is to proxy a non-TLS crossbar instance behind NGINX, which is documented in many places, for example: [https://stackoverflow.com/questions/12102110/nginx-to-reverse-proxy-websockets-and-enable-ssl-wss]
