"Could not connect to the host", WTH?

[Durgard]

Hi folks.

I'm running the game as the GM, we already played 3 times without any problems.
But, since 2 weeks, all my players have the same problem : "Could not connect to the host. Check check the address and try again"

All is Ok with my version (I have the lastest updated ultimate version).
All is Ok with my firewall (all rights and buttons are OK).
All is OK with my Internet or connection.

Can you help me pls ??
I'm disappointed.

Your IP probably changed for the port forwarding information.

What can I do to check if it's the problem?

Not an easy one to answer since it depends on your system. If you are on wifi then check that your router is set to forward incoming traffic to your computer's IP address. You can check the Internal IP address from the start screen in FG.
