I’ve reproduced step by step this guide : https://www.digitalocean.com/community/tutorials/how-to-allow-remote-access-to-mysql
But even after that, my port 3306 is still said as closed.
I’ve did the same thing on a second droplet, and that worked like a charm, whereas they both have really similars environements.
I already know that ssh tunnel is a better solution (in terms of security) but I need to use multiple databases in php files so it’s way too complicated to use multiple tunnels with different db in native language without extensions ect.
I’ve checked my mysql log, no errors. Both conf of mysql in each vps are the exact same. I’m completely lost guys 😭

Hi there,
I could suggest chaning the
bind-address = *
to0.0.0.0
instead as described in the tutorial:After the change, restart the MySQL service and give it another try.
If this still does not work, do you by any chance have any other firewalls that might be causing the problem? If you were to try and run
telnet your_server_ip 3306
are you able to connect or is it only the PHP script that is failing?Best,
Bobby
