Multiserver setup dns new server cron.log PHP Warning: mysqli_real_connect() expects parameter 1 to

Hi,
I've recently done a multi server install joining a dns server to an existing ispconfig install.
I am not seeing any DNS bind files on the new server.
I do see the DNS and DB on the system services screen.
I do see the error in the cron.log
PHP Warning: mysqli_real_connect() expects parameter 1 to be mysqli, null given in /usr/local/ispconfig/server/lib/classes/db_mysql.inc.php on line 275

I'm running ubuntu 18.04 LTS
php 7.2.19
I am able to connect to my master ispconfig db on the command line using root as well as ispcsrv4

I am running mariadb on the master and mysql on the slave

 

mysql -uispconfig -pxxxxxxxxxxxxx dbispconfig
successful

 

Hi Till,
I don't have a web interface running on the dns server is there another way to set the log level to debug from the command line?

 

You do it on the server with ISPConfig control panel. Choose the desired server, set debug level for that.

I'm not sure why but everything is working now.
Thanks for your help.
