I use a key (not password) to ssh into a server, but my IP address is frequently banned by the server.
After looking into the server auth.log, I found that someone (or some software) is trying every 10-20 minutes to ssh with the wrong password.

I'm using pycharm/phpstorm, etc., and created a Git server on my server.
I've checked the settings for these two software packages and have no idea what is happening. I even changed my computer, but it made no difference.
