ssh port 22 Connection refused 🐧 Linux

ssh: connect to host x port 22: Connection refused

The server answered, but nothing is listening on the SSH port — sshd isn’t running, it uses another port, or a firewall actively rejects.

Seen on: Linux

Meaning

“Refused” means a reset came back, so the host is reachable. Usually sshd isn’t installed/started (fresh VM, container), listens on a custom port, or fail2ban/ufw rejects your IP.

Common causes

  • sshd not installed or not running
  • SSH listening on a non-default port
  • Firewall rule rejecting (REJECT) your IP, or fail2ban ban
  • Connecting to the wrong host/IP

⚡ Quick fix

  1. Check from the console: systemctl status ssh
  2. Use the right port: ssh -p 2222 user@host
  3. Check ufw/fail2ban for your IP

Detailed fix by platform

Linux

  1. bash
    sudo systemctl enable --now ssh   # sshd on RHEL
sudo ss -ltnp | grep ssh
sudo fail2ban-client status sshd

How to diagnose

  1. Service — sshd running?
  2. Port — Listening port
  3. Firewall — ufw status / fail2ban banned IPs
