Step-by-Step: Troubleshooting a Website That Won't Load

A site that won't load has many causes; checking layer by layer from domain to server pinpoints it fast.

1. Scope it

  • Just you, or everyone? Use a third-party online checker or switch networks;
  • Whole site or one page?

2. Domain and DNS

  • Is the domain expired, and does it resolve to the right server IP;
  • Use ping domain to see the resolved IP; recent DNS changes may need time.

3. Server and services

  • Is the server online (ping IP);
  • Is the web service running: systemctl status nginx (or apache);
  • Are ports open: 80/443 not blocked by a firewall.

4. App and certificates

  • Check the web server error log (e.g. /var/log/nginx/error.log);
  • If HTTPS fails, check whether the SSL certificate expired;
  • For app errors check application logs and the database.

5. Still down
