I'm not sure you understand what I mean. The IP address of my mariadb container is 192.168.1.101, while my flarum container is 192.168.1.53. I'm just trying to find out where I can let flarum know that it needs to use the IP 192.168.1.101, to create a table under mariadb.
As far as the blank page goes, it's this.
