PuTTY returns Network error: Connection timed out, which affects users who try to remote into a server using this application. This issue can be frustrating as it prevents users from accessing their remote servers.

The network timeout error in PuTTY is often caused by poor internet connectivity or issues with the server's firewall settings.

⚠️ Common Causes

  • One main reason for this error is poor internet connectivity. When the connection speed between your local machine and the remote server is slow, it can lead to a timeout error. This could be due to various factors such as weak Wi-Fi signal, distance from the router, or high levels of network congestion.
  • Another possible cause is issues with the server's firewall settings. Sometimes, the firewall may block incoming connections from certain IP addresses, causing PuTTY to time out.

🔧 Proven Troubleshooting Steps

Check and optimize internet connectivity

  1. Step 1: Step 1: Check your local machine's network connection speed using an online tool such as Speedtest.net. Ensure that the speed meets the recommended requirements for remote access (at least 5 Mbps upload and 10 Mbps download).
  2. Step 2: Step 2: Verify that you are connecting to the correct Wi-Fi network at your dad's house. Try connecting to a different network or using a mobile hotspot if necessary.
  3. Step 3: Step 3: Restart your router and modem to ensure they are functioning correctly.

Check server firewall settings

  1. Step 1: Step 1: Contact the server administrator and ask them to check the firewall settings. Ensure that incoming connections from your local machine's IP address are allowed.
  2. Step 2: Step 2: If you have access to the server, try connecting using PuTTY and see if the issue persists. This will help determine if the problem is with the firewall or not.

🎯 Final Words

To resolve the Network error: Connection timed out in PuTTY, first check and optimize your local machine's internet connectivity. If that doesn't work, investigate the server's firewall settings to ensure they are allowing incoming connections from your local machine.
