Connection Timeouts or “Connection Refused” errors typically indicate a network-level issue between your machine and our proxy gateway. Here’s how to troubleshoot it.

​
Step 1: Verify Host and Port

First, ensure you are using the correct host and port number for your proxy.
  • Host: proxy.catproxy.net
  • Port: 5555
A common mistake is using the wrong port number or misspelling the host.

​
Step 2: Check Your Firewall

Your local machine, server, or cloud provider (like AWS or Google Cloud) may have a firewall that blocks outgoing connections to specific ports.
  1. Check your local firewall rules (e.g., Windows Firewall, ufw on Linux).
  2. Check your cloud provider’s security group rules. Make sure that outgoing (egress) traffic is allowed to the TCP port your proxy uses.

​
Step 3: Use a Network Diagnostic Tool

You can use a built-in tool from your command line to check for basic connectivity. 
nc -zv proxy.catproxy.net 5555
  • If the connection succeeds (nc shows succeeded, PowerShell shows TcpTestSucceeded: True): your network path is fine. The problem is likely in your script’s configuration.
  • If the command hangs or reports a failure: there is a network block somewhere between you and our gateway. Re-check your firewall rules.
If you’ve checked all of the above and the issue persists, please contact our Support Team and provide them with the output of your diagnostic tests.
