Why am I getting a No route to host error with a non-standard port?

Question

SSH

If I change the standard port 22 on the server to something else, then for some reason, when I try to connect, I get:

ssh -CYl root -p ПОРТ site.my
ssh: connect to host site.my port ПОРТ: No route to host

Why?

Answer 1

it shouldn't be like that. We need more details where and how they changed it, with examples of normal connections and examples of errors directly from the console.
