your console.log says:
AddPortMapping(28000, 28000, 192.168.1.66) failed with code 718 (ConflictInMappingEntry)
This seems to mean port forwarding is already setup because it says ConflictInMappingEntry
so you need to turn off uPnP or turn off port forwarding. you cant have both on at the same time.
Also make sure you pick "internet game" when starting your server. your log file shows:
AUTHCHECK: Clockwork = LAN client -> internet server, auth with server ip
