Troubleshooting the “Connection to the Game Failed” Error in Sniper Elite 3

Rebellion Developments’ Sniper Elite 3 remains a popular tactical third-person shooter, but players on PC, PlayStation, and Xbox occasionally encounter a frustrating roadblock: the “Connection to the game failed” error when trying to join a co-op or multiplayer match. This article breaks down the most common causes and provides step-by-step solutions.

Part 7: The Ultimate Checklist (Print this)

Before you give up, run this checklist:

[ ] NAT Type: Is the host’s NAT Open? (Yes/No)
[ ] Ports: Are UDP 27015-27030 forwarded? (Yes/No)
[ ] Firewall: Is SniperElite3.exe on the exception list? (Yes/No)
[ ] Steam: Are both players online and visible? (Yes/No)
[ ] DLC: Do both players own the exact same DLC packs? (Yes/No)
[ ] Save File: Have you deleted the Network Cache? (Yes/No)
[ ] VPN: Have you tried Radmin VPN / LAN mode? (Yes/No)

4. Port Forwarding (Router Configuration)

Sniper Elite 3 uses specific ports for P2P connectivity. Forward them to your computer’s local IP address.

| Protocol | Port Range | Purpose | |----------|------------|---------| | TCP | 27015-27030 | Steam P2P / matchmaking | | UDP | 27000-27031 | Steam P2P / game traffic | | UDP | 4380 | Steam’s legacy P2P | | UDP | 7777-7778 | Game-specific traffic (reported by players) | sniper elite 3 connection to the game failed top

Note: The game uses Steam’s P2P networking – forwarding Steam ports often resolves the issue.

How to forward:

Find your router’s local IP (usually 192.168.1.1 or 192.168.0.1). Login credentials are often on the router label.
Locate Port Forwarding (or Virtual Server) in the advanced settings.
Create rules for the ports above, pointing to your computer’s local IPv4 address (find via ipconfig in Command Prompt).
Save and reboot the router.

Final Thoughts

The “Connection to the game failed” error in Sniper Elite 3 is almost always a local network issue, not a bug in the game itself. By opening the correct ports, verifying your NAT type, and temporarily disabling IPv6, the vast majority of players can get back to blowing up Führers from 500 meters. [ ] NAT Type: Is the host’s NAT Open

Step 3: Check Your Internet Connection

Ensure that your internet connection is stable and fast enough to support online gaming. You can check your internet speed using online tools such as Speedtest.net. If your internet connection is slow or unstable, consider upgrading your plan or contacting your internet service provider for assistance. you cannot host.

5. NAT Type & UPnP

A Strict or Moderate NAT type will prevent connections.

Enable UPnP (Universal Plug and Play) in your router’s settings. This allows automatic port forwarding.
If UPnP is unstable, disable it and use manual port forwarding (above).
To check NAT type: In Sniper Elite 3, go to Options → Network – it will display NAT status.

1. Primary Causes

| Cause Category | Specific Reason | |----------------|----------------| | Server-side | Official matchmaking servers are offline, under maintenance, or experiencing high load. | | Network Address Translation (NAT) | Strict or moderate NAT type prevents peer-to-peer (P2P) connections. | | Firewall / Antivirus | Software blocks the game’s executable or required ports. | | Port forwarding | Required UDP/TCP ports are not open on the router. | | Game version mismatch | Host and client have different game updates or DLC packs. | | Steam / platform issues | Steam’s networking layer, overlay, or download region conflicts. | | Save data corruption | Corrupted local profile can block matchmaking. |

The Host/Joiner Swap

In SE3, the game is NOT server-based. It is Peer-to-Peer. If you have a strict NAT (Network Address Translation) type, you cannot host.

The Fix: If you are trying to join your friend and failing, have your friend try to join you instead.
Strict NAT Detection: On Xbox/PS, run a network test. If it says "Strict" or "Moderate," you cannot host. Only the player with "Open" NAT can host the lobby.

What Does the Error Mean?

The message “Connection to the game failed (Top)” — often abbreviated by players as “top error” — indicates that your game client cannot establish or maintain a session with the host’s machine or the official matchmaking servers. Unlike a simple timeout, this error typically appears immediately after attempting to join a specific lobby.
