Symptoms

The Game seems to run in Single Player Mode.
But it is not possible to host a coop session, to play with another player in coop.
In the main menu of the game, I tried this:

• Choose "Campaign" --> "Coop" --> "Host Game" --> "Create Lobby"

Then, after a few seconds, it gives the Message "Network Request failed. (unknown error)"

I tried this yesterday and today, also the one I wanted to play with tested it (similar PC with Kubuntu).

Reproduction

Just follow the steps mentioned above :-)

Start with the reported Steam AppID 817540, Proton 4.11, and the attached steam-817540.log. Reproduce the Campaign → Coop → Host Game → Create Lobby sequence and inspect the reported “Network Request failed. (unknown error)” behavior. Done means a cooperative lobby can be hosted successfully.
