I've got a working domain for my Raspberry Pi to which I can ping to. I forwarded the port for SSH (Port 22) on my router as well, but I still cannot connect from outside to my Raspberry.
Connecting to it via the local IP address in the local net works perfectly fine.
However, ssh [username]@[domain]
is not working. Connection refused to port 22. I'm using Ubuntu. Have you got any ideas?
