Wordpress not working with frontend and backend networks.

[corneliusmixon]

I like to create a backend network for the containers to communicate and I expose the frontend to my LAN with a macvlan. I have accomplished this on a few other compose files without issue. But I'm having an issue with Wordpress. When I test with just one network, everything works. I'm using the bitnami image in this file but I get the same result with this image. Can someone tell me what I'm doing wrong here? https://pastebin.com/J7B89Mz6
