My instance fails to start

So my Instance just randomly crashed and after restarting it says: Ghost was able to start, but errored during boot with: connect ECONNREFUSED ::1:3306

This is the debug log if it helps:

3306 is the port for MySQL. Is it running?

Yeah seems to be running when i do sudo service mysql status.

Anything in the MySQL logs? Any new firewall rules?

I added port 3000 with ufw allow, but this shouldn’t impact port 3306?
