Self built docker image mobile issue

[matthew11j]

Hi everyone,
I recently forked this repo to self host a simplified version of tandoor for me and my partner. As a test, without making any changes to the code, I built a docker image and deployed it using portainer on my home network. I used the Plain docker-compose file in the documentation and replaced the image with the one I built.
Everything worked great on my desktop and another laptop, until I tried to load it on my iPhone, I was able to hit tandoor, the sign in form appeared and I logged in successfully. After that though, no pages will load. I can see the navigation bar on top (but not on bottom) and can travel to different urls but nothing loads. This happens on chrome and safari.

For a sanity check, I created another stack on portainer using the exact docker-compose file that has the default image and everything works properly on my phone using that instance.

Any ideas on what might be causing this? I've tried messing around with some CORS settings and it almost seems like whenever a page is hitting the Postgres database, that's when nothing loads.

Thanks!
