How to Fix ASA SteamCMD Update Stalls & Port Conflicts

When hosting an ARK: Survival Ascended dedicated server, SteamCMD may occasionally stall at 99% or fail to bind to UDP ports 7777 and 27015. Here is the exact procedure to resolve these issues.

Step 1: Clear SteamCMD Cache

Run the following PowerShell command as Administrator:

Remove-Item -Recurse -Force "$env:LOCALAPPDATA\Steam\htmlcache"

Step 2: Bind Unique Server & Query Ports

If running multiple server instances on the same host machine, offset your ports:

• Instance 1: Port 7777, PeerPort 7778, QueryPort 27015
• Instance 2: Port 7779, PeerPort 7780, QueryPort 27016
