Apparently through my searches it seems that port 3306 is blocked, however before it was normal, I tried to add it in the rules even though it still did not work, anyone would know how to help me?
Are you getting this error on application side or control panel side?

From the application side, try my website all the air.
Do you have MySQL running?
systemctl status mysql
It not, you should run
systemctl start mysql
