Resident Evil 6 Failed to Join Session

[NerdBear]

I just bought this game during the steam sale. A friend and I have been trying to play it co-op but we both keep getting Failed to join Session/connect. I can join other players and other players can join me but we can't join each other which is very odd. Is there any fix for this?
I've been googling to find answers but they're all in 2013.. I would like to think by 2016 there was a proper fix or update for the game.

You simply try again. The host can recreate lobby if it doesn't work for a couple of times.

It's more than a couple times. It's EVERY single time (10 out of 10 tries sometimes more). It's rather annoying. We do recreate often and we still get the same problem.

What's the ping between you two? The game is using Steamworks for matchmaking. Can your friend connect to other people? If not then some port forwarding might needed https://support.steampowered.com/kb_article.php?ref=8571-GLVN-8711
One of you can also try creating an open session while other manually searches in lobby list and then connects through it.

If nothing works try changing Steam's download server in settings. And both of you should pick the same one.

My friend can also connect to other people. This is the only game we have trouble on in steam. We can connect to each other completely fine in other games through steam like L4D2 for example. However when my friend logs I'll see about port forwarding and changing the download server settings. Thanks, I'll keep this post updated if it works or not.

I'd suggest trying the last solution first. It requires a Steam restart, though. It can "magically" fix connectivity issues in Steamworks games.

Well, we tried changing our download settings to several locations (but both the same) and the problem still persists. When i'm trying to connect to his room from invite it will say failed to connect to session same with him when trying to connect with me. Searching through the panel of rooms we still have the same problem. :/

We can connect to anyone pretty much but each other lol (only in this game) so it really doesn't make much sense.

There's been exactly same issue 2 years ago.

And your problem is very unique and makes no sense. I don't think I can able to suggest any useful fix (maybe wiping the game, moving it to other partition, disabling firewall entirely, connecting internet directly without a router, putting router in DMZ).

There's 1 workaround if you desperate enough.

This guide shows how to make local coop work online that is if at least one of you has a decent nvidia card.

Download location has nothing to do with making possible to join on net, it is only for download games. You need both to restart the game each time you gonna play together, both need to start chapter or continue, and both create lobby, then 1 who wants to host press R and invite. If someone lost connection during the game, will be impossilbe to join session again. You need both to restart the game and create session again. At least that is how it works for me.
You said, you could join other players. Maybe your case is different than mine. Try anyways. I have game set to "only friends".

You'd be surprised, but sometimes it actually works.

your welcome to add me if u like to play some re5 or re6 i love them both!

I was looking for reply, if the user solved the problem and I saw your reply, Dfactor. Really?
I never was bothered what download location I have set while play games. I do not think that it does matter but I will considerate this, if I get the problem.
Otherwise, your advice : "putting router in DMZ" can not be possible, cause Steam does not support this.

Games for Windows live was bad, but when I played this game through it, at least, we could join and re-join, and we had not to replay alone parts so be able to re-join again. Game saves only at special points.
Thanks for Steamworks, of course, as GFWL does not exist anymore, but it is not well done.

I've used DMZ several times when playing with a Chinese friend via RE6. And the ping between us seemed better, less network lag. Steam still does function with DMZ enabled, I also tried on L4D2 a few times.
