Port 22 error!

Install & Config
#1

hello everyone, I have an error with port 22, my private server is in Digitalocean (Debian10), from the terminal “Putty” I have opened port 22, when reboot it generates an error when entering “time out”.

How can I correct this error?

thanks and regards

Wrong forum for such questions, you better ask on DO forums someone to help you there.
