What's changed
With a token for the wrong App ID, the server falls back to LAN only and players can't find it.
Never use App ID 740: Steam refuses tokens made for it.
New CS:GO Legacy servers are set up for 4465480. If your players use csgo_legacy, ask support to switch your server to 730.
When a server stops with the LAN-only message, the crash hint in your dashboard now points to the token.
