It start to join, has the loading bar for joining server but never joins. Infinite loading screen. Anyone experiencing the same issue?

Hi, this issue happens if trying to join when still on the battleship. Enter the first mission and once the cut scene has finished, your friend can join without issue. (Had same issue and this was the solution.)

What about operations?

[Irrigatio]

same issue here - we just switched around and had him join me instead to fix it for now

Not tried operations yet, but that worked for the campaign.

Doesn’t work just tried it

My buddy and I were having the infinite loading bug when trying to join each other. We found that if your friend is stuck in an infinite loop, you can transfer ownership of the party to them. They'll then load in and you will load into their world, then they can transfer it back if needed, and then you both will load into your world again. Hope this helps!

we got ours fixed by disabling the crossplay in title screen
and was able to join friends' sessions almost immediately.

Anyone telling you to get a vpn is advertising. It doesnt fix it

Another thing i noticed with this bug is that, my wife is trying to join my session, when she is joining my game would freeze. But when my cousin from another country joins it is no problem. I wonder what's wrong with this.

If your game is on Steam, disable the cross platform and join ur friends via Steam directly, on the contact list. It worked for us

I'm going through every thread and posting the actual fix for this issue. It requires some minor knowledge of changing router settings however.

1.Go to your router's default gateway. You can find this by opening a command prompt in windows and typing "ipconfig" without the quotes.

2.Take note of your IPV4 IP and your default gateway. Type the default gateway IP into a web browser. If chrome doesn't work try firefox or edge.

3.You will have to know your user name and password to access your router. If you don't know it you can search for your routers default login credentials on google. It should work if you or someone else has never changed the defaults. You can also look up your routers name and model along with "port forwarding" in google. This will usually lead you to an official page or document from the manufacturers website.

4.Majority of the time, these next settings are in the Advanced tab. What you're going to need to look for is Port Forwarding first.

5. Create a new service, port, whatever your router says and enter the following.
-Service Name: (Whatever you want)
-Protocol: TCP/UDP
-External Port Range:27015,27031-27036(this port range is for Steam, look at the end of this guide for PS5 and Xbox Series X range)
-Internal IP Address:(Your IPV4 address you made note of back in step 2)

6.Apply, Save, or Add, whatever your router has to finish. You should see it in the list of your forwarded ports now.

7.This next option you may also have to look around for. For me it's in the advanced tab under setup. You're looking for your "WAN Setup" or you may have something like "NAT Setup" or just "Nat."

8.Once you find the option, you should see "NAT Filtering." Make sure "Disable SIP ALG" is not checked or on, and make sure the NAT Filtering is Open.

9.Apply the settings and walk your friend(s) through it as well. You'll have to have these router rules setup on both sides. This is required for Steam and Console players. here are the other setups for part 5 for Playstation and Xbox.

Warhammer 40,000: Space Marine II - Playstation 5
TCP/UDP: 3074, 3478-3480

Warhammer 40,000: Space Marine II - Xbox Series X
TCP/UDP: 88, 500, 3074, 3544, 4500

Now go serve the Emperor!

Happened to me today, I turned off cross platform on main screen and inverted via steam then it worked perfectly
