ActivityPub Fails to Load When Self-Hosting ActivityPub and Ghost with Separate Admin URL Configuration

[vgit5989]

Issue Summary

I am self hosting Ghost 6 using docker and also want to self host the activity pub. I have made the necessary changes to the docker config and env files for this setup.

Main url: blog.testing.site.local
Admin url: admin.blog.testing.site.local
This is with the official ghost, my sql, activity pub, activity pub migrate, and caddy containers

My current setup with ghost 5 is ghost, my sql with routing managed by traefik
I have the same issue when swapping caddy with traefik, in ghost6, the activity pub does not load

I will attach the log file and relevant config files below

Steps to Reproduce

1. Setup Ghost docker compose according to the guide on: https://docs.ghost.org/install/docker#troubleshooting-docker
2. Enable ActivityPub in the env file
3. Set separate Admin url for Ghost
4. Access Network tab from the admin console using the Admin URL
