[FIXED] how to fix mysql 2003 timed out error on ubuntu server?

Issue

I can't make other PC connect to my server with mysql. I already set bind-address = 0.0.0.0

netstat:

root@localhost:~# netstat -nlt | grep 3306
tcp6       0      0 :::3306                 :::*                    LISTEN

telnet:

root@localhost:~# telnet liortesta.cf 3306
Trying 104.254.244.201...

2003, "Can't connect to MySQL server on 'liortesta.cf' (timed out)

I don't know what to do

Solution

Sorry, server provider also has firewall and it blocked my connections
