Hello all, Please I need help with the following problem. I have a multiserver setup in Debian 11. I upgrade to Debian 12 following the tutotial. Now, I am trying to update ISPConfig to use Debian 12. I update the panel server without problem. Now, when I run ispconfig_update.sh --force in any slave server I get the following msg: MySQL master server hostname. I point it to panel (master), port 3306 with the root and password but does not work. then I get: Unable to connect to mysql server Connection refused I tried connecting locally with root/pwd info from other servers and login works. I checked firewall and ports are opened. I check listening port and it is good. Servers are in the same subnet (nothing has changed from before). All Servers were working with not error. When I login web interface, there is not error or warning in any of the server. Than you
You can test the connection to the master using the mysql command, run it on the slave node: mysql -h master.server.tld -u root -p dbispconfig and enter the password that you created on the master server as root password for the connection from this specific slave node. Replace master.server.tld with the hostname of the master. The user must be root. if this does not work, fix root account for this slave node in the master mysql server e.g. using phpmyadmin.
