What to Do When Your VPS Won't Connect (SSH Timeout)

A failed SSH connection is one of the most common issues. Don't panic — work through the steps below and most resolve themselves.

1. Verify the basics

• Are IP, port and username correct (default port 22);
• Is the server powered on/running (check the console).

2. Timeout vs refused

• Connection timed out: network unreachable, usually a firewall, security group, or a down server;
• Connection refused: server reachable but SSH isn't listening — service down or wrong port;
• Permission denied: network is fine; an account or key problem.

3. Check item by item

• Try a different local network (phone hotspot) to rule out local blocking;
• Check the server firewall/security group allows the SSH port;
• Use ping/mtr to check for loss;
• If you have a web console (VNC), log in and check sshd: systemctl status sshd.

4. Still stuck
