How to Check if a Game Port Is Blocked — No Network Expertise Required

Blocked game ports are a common reason players cannot connect or experience high latency. You don’t need to be a network engineer to check and monitor them. UptyBots simplifies port monitoring for everyone.

Why Game Ports Matter

Online games rely on specific TCP or UDP ports. If blocked, your server may appear online but connections fail, causing frustration and lost players.

Simple Ways to Check Ports

• Use built-in tools like `telnet` or `nc` (Netcat) to test connectivity
• Try accessing the port from multiple locations or devices
• Check firewall settings on server and local networks

Automated Monitoring with UptyBots

• Continuous TCP/UDP port checks from global nodes
• Alerts when ports are unreachable or response times are too high
• Logs and graphs for historical visibility and troubleshooting

Preventing Connection Issues

• Document which ports are required by your game
• Include port monitoring in your uptime strategy
• Set up notifications to act immediately when a port becomes unreachable
