Seen on: Apache Linux

Meaning

Find the owner: sudo ss -ltnp | grep ':80', stop or reconfigure it (change Listen in ports.conf), and start Apache again. A leftover Apache process from a crash can also hold the port: sudo pkill apache2 then start.

Common causes

  • Nginx or another web server already on port 80/443
  • Stale Apache child processes
  • Duplicate Listen directives (80 twice)
  • Docker container publishing the port
  • Hot restart race

⚡ Quick fix

  1. sudo ss -ltnp | grep -E ':80|:443'
  2. Stop the other service or change Listen
  3. Remove duplicate Listen lines

Detailed fix by platform

Linux

  1. sudo ss -ltnp | grep ':80 ' && sudo systemctl stop nginx

How to diagnose

  1. Owner — Which process?
  2. Listen — Duplicates?
  3. Stale — Old Apache?
