anonymous login for server updates stopped working for some reason, the issue are probably changes on the Steam side. The SteamCMDLauncher.bat has to be edited to log in with valid Steam credentials. This line:
“WHATEVER\DedicatedServerLauncher\SteamCMD.exe” +force_install_dir “C:\Users\swage\OneDrive\Desktop\DedicatedServerLauncher\ConanExilesDedicatedServer” +login anonymous +app_update 443030default +logoff +quit
“anonymous” has to be changed to a valid Steam account name (yours). It will ask for a password. Be sure to edit the line without ECHO there are multiples. That is it.
