In addition, outdated router firmware (especially in Netgear routers), corrupted game files, or interference from Windows Firewall may also trigger this error. In this guide, we’ll explore several effective solutions to help you resolve the issue.
1. Set “Synchronize System Time” to Automatic
Game servers use timestamps to authenticate session requests and match them with server-side data. If your system clock is out of sync, the game may reject your connection thinking it’s invalid or expired, which leads to disconnection issues like the “Lost Connection to Host” error. Enabling automatic time synchronization ensures your system clock stays accurate, which can help prevent connection errors.
2. Disable IPv6
Although IPv6 is designed to improve networking, it may occasionally conflict with specific server configurations. Disabling IPv6 can help resolve connectivity issues with certain games.
3. Verify Integrity of Game Files
Corrupted or missing game files can lead to connection errors. Verifying game file integrity through Steam helps detect and repair these issues.
4. Flush DNS Cache
Over time, your system stores outdated DNS information, which can lead to connection issues with game servers. Flushing the DNS cache clears these records and allows your computer to fetch fresh data from the internet, potentially resolving the error.
5. Use Google DNS
Your default DNS server (usually provided by your ISP) may be slow or unreliable when connecting to specific game servers. Switching to Google’s public DNS can improve server resolution speed and network stability.
6. Add Game to Firewall Exceptions
Windows Firewall may block the game’s communication with its servers. Manually adding the game to the firewall exception list allows smoother network communication and prevents disconnection issues.
7. Forward Required Ports (Advanced Users Only)
If your network blocks certain ports, the game may struggle to maintain a stable connection. Port forwarding helps by manually opening the necessary ports, allowing uninterrupted communication between your PC or console and the game servers.
8. Update Router Firmware (Advanced Users Only)
Keeping your router’s firmware updated improves network stability, enhances performance, and resolves known bugs. This can help reduce disconnections during gameplay.
