Version mismatches between client, server, and mods cause disconnects/crashes. Ensure sync via TCAdmin Startup tab at fpsdedicated.com.[docs.tcadmin]
Server vs Client
Must match exactly.
-
Update server: Startup > Game version dropdown (SteamCMD pulls latest).
-
Clients auto-update or manual via Steam. Mismatch: "Server version outdated" kicks.
Server vs Mod
Mods tie to server build.
-
Check mod page: "Rust 2026.1 compatible."
-
Update server first → test mods (console: version errors). Outdated mod? Disable/update.
Client vs Mod (Workshop)
Subscribe required.
-
Steam Workshop: Clients subscribe ModID (panel auto-manages server side).
-
Non-workshop: Manual client install matching server files.
Verification
-
Logs: "Mod mismatch" or kick reasons.
-
Test join with alt account. Nightly/experimental? Label clearly. Mismatches = rollback server/mod. Ticket for bulk updates.[youtube]
