When I create a daemon for App API, the following happens
Default Deploy Daemon is not accessible. Please verify its configuration.
Console outputs the following:

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 - 
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
