Hey everyone,

Me and a friend having serious problems setting up a multiplayer coop session.
Our "environment":
------------------------------------------------------------
-We both have IL2 1946 (4.13.4) from steam
-We both have SAS_Modeact_6.40_for_IL-2_4.14.4m
-We both have SAS_JSGME_Options_for_Modeact_6.4x
    (We have both no Singleplayer problems with this setup, it was a fresh install)
-We use Hyperlobby with a Server on Port 21000
-We both forwarded UDP/TCP 21000 in our routers.
-We both checked our firewalls, so the game and the ports aren't blocked on our machines
-------------------------------------------------------------
Our problem:
-------------------------------------------------------------
We can find each other in hyperlobby and we can start a game.
But everytime when one tries to connect to the others server, the game starts for both of us but the joiner gets a timeout in IL2.
-------------------------------------------------------------

Are we just too stupid and missing something important here? Has someone maybe experienced this problem and knows how to fix it?
I reaaally would love to play this game in MP, so any help would be highly appreciated.

best regards

Did you try a different port?
Are you sure you're not behind a carrier grade NAT?
For the latter, compare your router's external IP with the one shown here: https://www.whatsmyip.org/

Hey Mike,

thank you for the reply! I tried 21000 and 21001. I am not sure about the "carrier-grade" part, because I don't really know what that means, but my router is a regular fritz-box with NAT. Also the ipv4 address in my router (which is active) is the same as the address shown on whatsmyip (It's not a fixed public address though, so it changes every day).

I also play other MP games on this setup where port-forwarding is necessary and it works just fine that way. Is there maybe anything that must be changed in conf. ini or hyperlobby. def?

best regards,
Eric

I just realized that the whole time I tried to host with a self-builded coop mission. I automatically assumed that it will be downloaded by the client. Could this be the problem?
And must the setup in JSGME be exactly(!) the same on both machines, even when the regarding mods(that differs on both machines) are just for "cosmetics"?

... I guess I should come back to you after more testing.

best regards,

It's been ages since I've hosted a game from within the Client.
Maybe someone else can jump in and give proper hints.
