New install of AllstarLink works, but have errors on launching Allmon3

I am trying to set-up a private internal server for three nodes and Allmon3 gives errors.
Dell Optiplex 380, debian12 OS, AllStarLink3 & Allmon3.
When launching Allmon3 these errors are received:
INFO: (allmon3) starting node_db updater
INFO: (asl_allmon.node_db) Retrieving database from https://allmondb.allstarlink.org/
Traceback (most recent call last):

Is there a configuration error in the set-up or do I have a corrupted Allmon3 binary?

Does the system have network connectivity?

Can you ping -c 4 allmondb.allstarlink.org ?

You either have two instances of Allmon3 running or something else is using port 16080.
