Online Co-Op Connectivity

[Foggdogg]

So I bought this game for my game group, and in trying to play it together, none of us can connect to each other to start a game. We almost instantly get a "cannot connect" message. We've hit the button in the top right and selected "go online", used steam to send invites, and still have no success.

Has anyone else had trouble? What did you do to correct this?

I haven't had issues with *this* game before, and I've done online mode a couple of times.

Usually with steam games and internet issues, one of the following is going on:
1. Someone is invisible instead of online
2. Someone needs to update their steam client
3. Someone is having internet connectivity problems

Usually, if everyone restarts their computer, updates their steam client, and is in Online mode without issues elsewhere things will work. Restarting the internet can help if someone has a bad connection overall.

If Gacha Pawn's suggestions don't work, please try out having different people hosting - it's possible that a specific machine is the issue, e.g. due to a firewall blocking access.

Also please try out joining someone via the Steam friends list (e.g. in the shift+tab overlay). If someone is playing online you should be able to right click them and choose 'Join Game'. Does this option appear?

What is the exact message you're seeing when it fails?

[Foggdogg]

"Failed to connect to the host. Please try again."

It appears to be a host issue, and only one person in our group seems to have success as a host.

Does anyone know what ports need to be open to host this game? Or if it's picky with strict NAT rules, or something of the like?

Thanks!

Hi Foggy
I'm on the dev team so would like to join in.

The game will give that message in all sorts of situations. The tech behind connections on Steam is very much using the Steam system for almost all the complicated stuff. This all means that if you've got NAT troubles or Port issues, then you'd have them with loads of other steam games as well.

Our system will reject connections if you're not on the same version (double check for updates, perhaps even have a look in the main title screen at the v1.0.X.X value in the top right)

If that all looks the way it should, then it's starting to get mysterious...

The game doesn't require very much internet speed, but some things like 'authentication' (two machines doing a virtual handshake) have reasonably strict 'time out' values. I know this sounds like the lamest suggestion, but do you have very unreliable wifi? What happens if you go real close to the router or use a wired connection?

In a real bind, I would venture to either reinstall the game - maybe something weird has happened or *try* a clean save (again, maybe something weird is going on).

When your friend who can host does, can you all join and see one another etc? do you have reasonable ping?

I'm sorry it's not working perfectly!

Hello!

I'm directly connected to my router, so no wifi on my end, and I really don't have problems with any other steam games. I was trying with my friend last night, and I can connect to him, but he can't connect to me when we're both at the same point in the game, right after the tutorial.

We'll keep trying things! I think he's set to private, so not showing the game he's playing, but I am not, I'm wondering if that has an effect (but not the way I would assume as-is) and I'll keep updating with findings just in case anyone else is having problems.

Thanks!

Hi Foggdogg
I'm sorry my suggestions didn't help. By the sounds of it you've got a peculiar problem I've not encountered before. The fact you can connect to your friend but he can't do vice versa is quite confusing to me.

You mention your friend being set to private, any lobby the game hosts should be capable of allowing players in if they have an invite, regardless of privacy. It might be something to check, and I'd certainly like to know if that IS having this effect.

Unfortunately I can't offer much help beyond the bodges i already suggested.

I wonder if you have the possibility to try either connecting from a different location (but with the same login / computer) or connecting from the same location but using a different computer / login? Maybe that will shed some light.
