I set up the server, forwarded the port, left - SSH does not work. What could be the problem?

Question

linux

I recorded the minibian OS image on SD, inserted it into the raspberry , saw a green light, changed the root password via SSH, forwarded port 22 in the router, and left for another country. Now I can't connect, what should I do? Perhaps access to SSH from the WAN is disabled by default? I can physically allow a neighbor to the server if I know what to do. There is access to the router, here you can see that the server is online:

Answer 1

look at the logs why the port was not forwarded.
I constantly go to work via ssh, it costs zyxel on it, tcp is forwarded inside lan.

Answer 2

What's the problem with checking what you've done right after you've done it? The same speed-tester.info allows you to check the port. Done, checked that everything works and left quietly.
