MongoDB does not open Port

After the restart of one MongoDB server, the process does not open a network port anymore.

In the log of the Firewall I found a connection from the MongoDB server to the NFS server on port 4045 UDP.
The Port is used for NFS lock daemon/manager.
I added the port to the firewall rule and restarted the service

In my possibility list above, I ignored the firewall as your server “was” working before the restart. I now wonder why it was working before the restart without the firewall rule

Anyways, it is a relief to know the problem is solved.
