Port 64294 (Cockpit) is used for sending data to Hive resulting in a port conflict.

The problem

Before 24.04.x the port 64294 was used for the Cockpit process. This process uses port 64294 on the host.
After updating to 24.04.x this port is used to send data to the hive as seen in the documentation. This results in a port conflict and the NGINX reverse proxy Docker container wont start.

The solution

If you want to keep using Cockpit change the listening port to another port. This can be done by editing /etc/systemd/system/cockpit.socket.d/listen.conf. After changing the port reload the daemon and restart the Cockpit process.

sudo systemctl daemon-reload
sudo systemctl restart cockpit.socket
