Can't connect to mySQL server after the hacker

My site has been down over ten days now since the hacker did his damage. He wiped out several tables in my database. Right after it happened I was still able to get into the mySQL server using my macOS Querious app, but not anymore. I’m not sure what the hacker did to cause this subsequent change. I can successfully get in if I use the command line to SSH into the droplet, then login with a user on the mySQL server. But I just can’t accomplish this in the mySQL app.

I’ve been researching this for days on end with no success. Can someone point me to an article that would help me troubleshoot this problem? I do have an inbound rule in the Digital Ocean firewall for port 3306. I also have this port open in ufw.

Here is the error I’m getting in the Querious app:

mySQL connection failed Can’t connect to mySQL server on x.x.x.x (61) (2003) Double check the mySQL host and port settings are correct, the server is running, and that no firewall settings are blocking access to the server.

Thank you!!
