Dedicated server Connection timed out

Hey guys, I’ve been playing on my dedicated server which i host on my pc, with my gf without mods all vanilla till last patch (Age of War). After last patch she can’t join to server keep getting “connection timed out! Could not find server” she can see server in server list, just can’t join, (I can join).
We are playing on same internet.
I tried to do exception in firewall, turned off firewall, direct connect, but still no luck.
Anyone has any idea how could I fix it ? Thanks.

Have you switched to dsl 1.7.1?

Yes, switched from 1.6.9 to 1.7.1 because of error “The game server executable could not be located”.

Fixed it by changing first 3 ports to higher numbers.
