Thanks.

It sounds like the port you’re using isn’t open, that’s the only reason I can think of that would explain it not showing up or connecting at all.

I would recommend mentioning your versions, including your OS.

That issue sounds like networking issues, be it firewall, port forwarding, or other routing issues.

I am stupid, i have the firewall ufw and i dont allow the port, was that, sorry by the inconvenience and thanks anyway by the help.
