I'm using Cloudflare tunnels on my Unraid server. I've successfully got a couple Minecraft servers and Overseerr working. I got Worpress and MariaDB set up and working fine locally. Because port 8080 was already in use, I set the Wordpress container to port 8089. I can open the Wordpress demo site up locally at 192.168.1.1:8089, but when I try to access it from the outside, page.mydomain.xyz:8089, I get an error message that the page is taking too long to respond. It somehow also seemed to kill my Overseerr interface. Now, when I try to go to overseerr.mydomain.xyz (port 5055), it times out and gives the same error for page taking too long to respond, and then shows the url as overseerr.mydomain.xyz:8089. I don't even have Overseerr set to that port. Alternatively, if I go to a previous url for Overseerr users page, overseerr.mydomain.xyz/users, the page loads fine. Any guidance is very appreciated.
EDIT: I'll add this from the Wordpress log screen:
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.XX.XX.19. Set the 'ServerName' directive globally to suppress this message
Does this help?
