Hmm... Could you try hitting start in your menu and going back into the mainmenu after the level loads then retrying next time this happens?

I've had it happen a couple times myself but retrying like that usually works.

Just tried jumping into a level and back out (a few times), doesn't help.

Issue still persists. Checked the output.log and it's cycling/repeating

"ConnectUsingSettings() failed. Can only connect while in state 'Disconnected'. Current state: Connecting

(Filename: C:/buildslave/unity/build/artifacts/generated/common/runtime/DebugBindings.gen.cpp Line: 51)

TimeoutDisconnect while connecting to: ns.exitgames.com:5058. Check if the server is available.

It looks like the game doesn't have access to the internet, which is odd.
Did you block it somehow? Or your computer?

Not that I'm aware of. It's allowed through both Firewall and AV. Interestingly, I have another game (Ironwolf VR) which has (presumably) the same issues, and it's also a Unity-based game. Those are the only games I'm having any issues with atm.

Hi,
I have the same issue, can't play multi.
I'm using an oculus rift with W10.

Have any idea?

Since this was revived, I should point out that it works for me now. That said, I changed nothing, so I don't really know anything more than before.

I think have found the solution.
Do not launch the game from Oculus Home (for oculus rift users) but first launch Steam VR and Climbey from SteamVR Home. It works for me !

Glad you were able to resolve it, sounds like a really odd problem.
Possibly something about the game not being able to connect to Steam which meant it errored out when you hit start server browser because it checks your steam username.
