How to Connect to Your Nuclear Option Server
Learn how to find your server IP and join your Nuclear Option dedicated server using the server browser or direct IP connect.
Here's how to find your server's IP address and connect to your Nuclear Option server. You can join through the in-game server browser or connect directly using your server's IP address.
Finding Your Server IP
Open the XGamingServer panel
Log in to the XGamingServer panel and select your Nuclear Option server.
Locate your IP address
Your server IP address is displayed in the sidebar (e.g., 198.137.23.46:7777). The number before the colon is the IP address, and the number after is the port.
💡 Tip: Click the IP address to copy it to your clipboard. You'll need both the IP and port to connect directly.
Using the Server Browser
The server browser is the easiest way to find and join your server:
Launch Nuclear Option
Open Nuclear Option from Steam.
Go to Multiplayer
From the main menu, select Multiplayer.
Browse servers
The server browser will display all available servers. Wait a few moments for the list to fully populate.
Search for your server
Use the search bar to find your server by name, or sort the list by player count, ping, or map.
Join the server
Select your server and click Join. If the server has a password, you'll be prompted to enter it before connecting.
The server browser shows useful information:
- Player count — How many players are online vs. max players
- Map/Mission — What mission or scenario the server is running
- Ping — Your latency to the server (lower is better)
- Lock icon — Indicates the server requires a password
- Game version — The version the server is running
Direct IP Connect
If your server doesn't appear in the browser, or you prefer to connect directly:
Open Multiplayer
From the main menu, go to Multiplayer.
Select Direct Connect
Look for the Direct Connect or Connect by IP option.
Enter your server details
Enter your server's IP address and port from the XGamingServer panel:
- IP:
198.137.23.46 - Port:
7777
Connect
Click Connect. The game will connect directly to your server.
📝 Note: If the server has a password, you'll be prompted to enter it after clicking Connect.
Adding Your Server to Favorites
After finding your server, you can save it for quick access:

Locate your server in the server browser.
Favorite the server
Click the star or favorite icon next to your server.
Access from Favorites
Your server now appears in the Favorites tab, so you can join quickly without searching each time.
Troubleshooting Connection Issues
If you can't connect to your server:
- Server not in browser — Make sure the server has fully started. Check
Consoleon the XGamingServer panel for startup progress. It can take a minute or two for the server to appear in the browser after starting. - "Version mismatch" — Your game client and the server are on different versions. Update your game through Steam and restart the server from the XGamingServer panel to pull the latest version.
- "Connection timed out" — Verify the IP address and port are correct. Try restarting the server from the panel.
- High ping / lag — Choose a server location closest to you and your players. Check the
Consoleon the panel for any performance warnings. - Password required — The server has a password set. Contact the server owner for the password.
- Game crashes on connect — Verify your game files through Steam (right-click the game in your library, go to Properties, then Installed Files, and click "Verify integrity of game files").
