Garry’s Mod server guide: join, mods, settings and fixes
Updated 31 October 2026 · 3 minute read · Garry’s Mod (PC) · By Exclsv Support
Everything you need to run your Garry’s Mod server in HQ, in one page.
Join
- Open the console with the ~ key.
- Type connect followed by the address from your server’s Join page, and press Enter.
Or find the server by name in Find Multiplayer Game.
Mods
Garry’s Mod servers download one Workshop collection when they start. Make a public collection on the Steam Workshop, then paste it on the Mods page; HQ checks it’s public and that every item is still there. Players download it when they join.
Settings
Open Settings, then Game settings. Each setting has a plain label, one line of help and the game’s own default where HQ knows it. Most changes take effect at the next restart; HQ marks the ones that change straight away. HQ makes the Steam login token the server needs to be listed.
Backups and going back
HQ takes an hourly backup (Automatic backups) and keeps each for up to 48 hours, plus an off-site backup every 6 hours with 7 daily copies. To go back, open Backups, then Automatic backups, pick a time and choose Go back. Your world as it is now is kept, so you can undo it.
If it doesn’t work
The Workshop collection didn’t download
Check it is public and every item is still on the Workshop.
An addon errors
The error line names the addon. Remove it from the collection, or update it.
The server isn’t listed
The Steam login token is missing or was revoked. Open Health on the Overview: it says what to do next.
