What I have I tried:
I have been following the following GitHub page for Docker in Trusted Network: GitHub - cloud-py-api/docker-socket-proxy: Nextcloud AppAPI Docker Socket Proxy. Where the command is

docker run -e NC_HAPROXY_PASSWORD="some_secure_password" \
  -v /var/run/docker.sock:/var/run/docker.sock \
  --name nextcloud-appapi-dsp -h nextcloud-appapi-dsp \
  --restart unless-stopped --privileged -d ghcr.io/cloud-py-api/nextcloud-appapi-dsp:release

I have also tried the advice here, including changing the owner of docker, but that caused more problems than solutions ( All ExApps are up-to-date. Default Deploy daemon is not accessible - :bento: Features & apps - Nextcloud community).

The docker is created with no problem, and I enter the following information to register the daemon for App API:
Name: docker_socket_proxy
Display name: Docker Socket Proxy
Deployment method: docker-install
Daemon host: nextcloud-appapi-dsp:2375
Hostname or path to access Docker daemon (e.g. nextcloud-appapi-dsp:2375, /var/run/docker.sock)
Nextcloud URL: http://cloud.example.com
Network: bridge (I have also tried to explicitly state the network as ‘host’ when making the container, and using that, but no luck). I also got the bridge name from inspect and the github.
HaProxy password: some_secure_password

I figured it out, turns out you need to use IPAddress associated with the container for the Daemon host section. I found it by using docker inspect and looking under NetworkSettings. I know this was a very obvious mistake, but hopefully this helps anyone else that makes the same mistake.
