xmpp service on port 443 and sslh complexity

PP Pirate Praveen Public Seen by 249

We started offering xmpp on port 443 to bypass stupid firewalls. But it added a complex piece of software sslh to the mix. With matrix service becoming popular and sslh configuration causing down times, I suggest we stop providing xmpp on port 443 (it will still be availble on 5222 and 5223 ports). If someone figures out a way to proxy this using nginx, we can consider this again. This will help us to get rid of sslh.
