How to Join Your Abiotic Factor Server
How to connect to your Abiotic Factor dedicated server via direct IP or the server browser.
Direct Connect (Recommended for PC)
Launch Abiotic Factor and click Enter The Facility → Join A Server.
Click Direct Connect. Enter your server IP and port (find it on the panel Dashboard).
Enter the password if required and connect.
Server Browser (PC)
Click Enter The Facility → Join A Server.
Search by your server name, select, and join.
📝 Note: The Abiotic Factor server browser is known to be slow — it can take 5+ minutes to populate. Direct connect is faster and more reliable.
Console Players
Xbox and PS5 players can only join via the in-game server browser — there is no direct IP option.
Launch Abiotic Factor and go to Enter The Facility → Join A Server.
Search for your server by exact name, select, and join.
Make sure crossplay is not restricted by -PlatformLimited in startup params. See Crossplay.
Troubleshooting
| Issue | Fix |
|---|---|
| Server not in browser | New servers take 2–5 minutes to appear. Use direct connect. |
| Version mismatch | Both client and server must be on the same version — update your server |
| Can't connect | Check IP and port. Verify ports 7777 + 27015 (UDP) are open. |
| Console players can't find it | They must search by exact server name. Check -PlatformLimited isn't set. |
Ports
| Port | Protocol | Purpose |
|---|---|---|
| 7777 | UDP | Game traffic |
| 27015 | UDP | Steam server browser |
