Apologies, but I am not sure where else to turn with this, currently running this in a podman container with quadlet.

The container file shows:
[Unit]
Description=The ghost container
After=local-fs.target

[Container]
Image=docker.io/library/ghost:5
PublishPort=2368:2368
Volume=/mymedia/docker/ghost/content:/var/lib/ghost/content
Environment=url=https://(full url)
Environment=database__client=mysql
Environment=database__connection__user=ghost
Environment=database__connection__password=(removed)
Environment=database__connection__host=(remote mariadb server)
Environment=database__connection__database=ghosty
Environment=server__port=2368
[Service]
Restart=always

[Install]
# Start by default on boot
WantedBy=multi-user.target default.target

This is behind an apache reverse proxy:

    ServerName (same as full url above)
    ProxyRequests Off
    ProxyPass / http://localhost:2368/
    ProxyPassReverse / http://localhost:2368/

Server starts, and shows ready, however :
curl -I localhost:2368
curl: (7) Failed to connect to localhost port 2368 after 0 ms: Couldn't connect to server
