Having issues with Multiplayer

[Rowley]

So, I've been trying to get started with a friend but we've been unable to get any connections thus far. Its been either one of two issues every single time, either it says we don't have the same version/checksum (2.3.6 (JWMQ) which we solve with repeated restarts, or when we do and he attempts to connect to me, he crashes immediately.

I'm playing with every expansion and he has none, which I assume isn't the problem. I am able to connect to other people's games without issue as well.

The only thing that comes to mind is the possibility that I need to forward my ports, though when I went to attempt it I hit the roadblock of being prevented from doing so due to having a static IP.

Any thoughts as to what I can do?

Expansions should indeed not be a problem. My course of actions would be;

- If any of you have made changes to the game files manually, reinstall the game.
- Make sure you both have a legit copy of the game.
- Both make sure you are on the same version, which should be 2.3.6.
- If you played a campaign of CKII restart game, cause it will have changed checksum.
- Make sure both of you guys wait till the checksum is calculated before hosting/joining the multiplayer game.

As for mods, things are tricky. I'de recommend you both disable all mods. Some mods alter Checksum. If you really wish to use a certain mod you must both have it installed.

Hope this helps.

In addition, both of you should try deleting the contents of /%username%/documents/paradox interactive/ck2/map

Hey, I tried both suggestions, and I'm still running into the same issue of my friend crashing whenever he attempts to join my game.

-We've both reinstalled our games
-We both own legitimate copies
-We're both on 2.3.6 and restart whenever we're not the same checksum letter
-Neither of us are using any mods, though I have all of the expansions, portraits, clothing and unit pack DLC
-As per Racketeer's suggestion we both deleted the contents of /%username%/documents/paradox interactive/ck2/map

I've honestly no idea what remains to be tried. :/

I've started trying again, though the only possibility that jumps out at me is that it has to do with my ports--as most guides state that its necessary to have them forwarded in order to host. My problem therein however, is that with my internet provider I don't have a static IP, so it seems impossible to forward said ports.

You may try sharing accounts with your friend and let him host if his IP is static. That will solve connection issues as well as allow you to play with dlc
