Solved: I was missing the .ico for the game. It is a 32x32.ico file. Once I uploaded the client image that and published the changes to steam it was able to create sessions. In order to test the server/lobby, I also had to create a key for my other test steam account so it would also have a valid copy. ---

I’m in the same boat. I just got my steam ID today and plugged it in. Now the build is saying the same thing. Can you please elaborate on this .ico file that you needed? Client image? I’m confused! lol ---

I had the same problem. I had already setup the .ico file, so that wasn’t my problem. Testing from my dev pc worked but another pc with a different steam account didn’t. What worked for me was to add that other steam account to the app: 1. Login to steamworks ([https://partner.steamgames.com/](https://partner.steamgames.com/)). 2. Go to Users & Permissions → Manage Users. 3. Click “Invite User” button and follow the process, which will do some email back and forth to invite/approve, etc. BTW: The .ico file can be edited by going to the steamworks dashbord → your app → Edit Steamworks Settings → Community → Assets. ---

Aside from the .ico I had to create default packages. To do this go to steamworks, click on your app, then “All Associated Packages, DLCs …” etc , Then on the top is a button named something like “Create Standard Packages”. Clicking this, and waiting a little made everything work! In other forum posts they say to contact steam, but it seems that they added a button!
