Step-by-step troubleshooting
-
Reboot devices
- Quit Black Ops III, power off your console/PC, wait 30 seconds, then power on and relaunch the game.
-
Switch to wired connection
- Connect via Ethernet to reduce latency and packet loss. If not possible, move closer to the router and minimize other network usage.
-
Test network and NAT
- Run the platform’s network test and confirm NAT type is Open (Xbox/PC) or NAT Type 2 (PS). If Strict/Type 3, enable UPnP on your router or forward ports (see Ports section).
-
Clear local game cache
- Console: Power-cycle the console fully and, if available, clear cached data (hold power button until off, unplug for 30s).
- PC (Steam): Verify game files (Steam → Library → Right-click Black Ops III → Properties → Local Files → Verify integrity).
-
Re-login / remove account token
- Sign out of platform account, restart, then sign back in. On PC, try removing local credentials for the game (if present) and relaunch.
-
Update or reinstall the game
- If verifying files fails, reinstall Black Ops III. Ensure saves/profiles are backed up if needed.
-
Check for background apps (PC)
- Disable VPNs, proxies, or firewall rules that might block game traffic. Temporarily disable antivirus to test.
-
Forward ports (if NAT issues persist)
- Common ports to forward for Call of Duty titles (platform-dependent; replace with your platform’s ports if different):
- TCP: 3074, 27015–27030
- UDP: 3074, 3478, 4379–4380, 27000–27031, 27036
- Enable UPnP on your router first; only use manual port forwarding if comfortable.
-
Wait and retry
- If servers are experiencing outages or maintenance, waiting 30–60 minutes and retrying often resolves the issue.
4.4. Verify Integrity of Game Files (Steam)
Corrupted game files can cause the UI module to fail when trying to handshake with the server.
- Open Steam Library.
- Right-click Call of Duty: Black Ops III > Properties.
- Navigate to the Installed Files tab.
- Click Verify Integrity of Game Files.
- Wait for the process to complete and launch the game.

- Delete the folder:
Steam\steamapps\workshop\content\311210
