It had everything to do with it, as more and more is being forced through HTTPS, because I don't know, it's more secure or it's the only port not being filtered. There were a few times I has to run sshd on port 443 (on a server I control---a preventive measure) because a network I was forced to use (a "public" wi-fi) only allowed ports 53, 80 and 443 outbound.
