dedicated server SOLVED - ark server not showing in LAN

[KriegTiger]

EDIT / SOLUTION - I edited the 4th group to be 7778, 27016, 27021 and that fixed it. Apparently the LAN queries will ONLY probe a very narrow band of ports and anything above the group 3 ports is ignored.

------

I've been running a small cluster of systems for a number of years. Up until now it's been 3 maps at a time, but I wanted to add the 4th (extinction) to the group. For the outside world, it's great. The servers are all visible in the Steam global/master list, all run perfectly as expected, and inter-map-travel is flawless. But on LAN, all I ever see are the first three.

This is the port assignment section of my config file for the map. I can comment out group 4 and uncomment ANY other group and it shows up perfectly on LAN, but using that 4th group it suddenly is never detected as a LAN available server.

There is no firewall to worry about, either on server or client.

#arkserver ports
#port="7777"
#queryport="27015"
#rconport="27020"

#arkserver2 ports
#port="7779"
#queryport="27017"
#rconport="27022"

#arkserver3 ports
#port="7781"
#queryport="27019"
#rconport="27024"

#arkserver4 ports
port="7783"
queryport="27021"
rconport="27026"

What's the deal?
