How to set up VPN and SSH for testing telegram bot?

Question

go

I am writing a bot, in the GO language, which will manage a remote server through commands, individually everything is done with a bang, but when testing the bot through vpn, the ssh connection to the server does not go through, I read the information they write something about the ssh tunnel, I would like to know Am I in the right direction? Or are there much easier methods? maybe somehow you can reconfigure ssh?
