ERROR! Failed to request AppInfo update, not online or not logged in to Steam.
I had the same error when I first time install the server, but somehow I mess stuff around and it was downloading files, but this time no matter what I do the error stays there...
I did tried to use google, did not find a solution yet, but I will continuing search. Thank you for helping if you got suggestions.
This new update method is such a pain, no idea why valve making a crappy updater instead of continuing use the steamupdatetool.
