Troubleshooting SSL Certificate Issues

Fixing Common SSL Problems

Solutions for SSL certificate errors and issues.

"Your Connection is Not Private"

  • Certificate may not be installed
  • Certificate may be expired
  • Wrong certificate for domain
  • Try requesting new Let's Encrypt certificate

SSL Certificate Not Issued

  • Verify DNS points to your server
  • Check domain is accessible
  • Ensure port 80 is not blocked
  • Wait for DNS propagation

"Mixed Content" Warnings

Some resources loading over HTTP:

  • Check for http:// URLs in your content
  • Update image URLs to https://
  • Check theme/plugin settings
  • Use "Better Search Replace" plugin for WordPress

Certificate Expired

Let's Encrypt should auto-renew. If expired:

  1. Go to SSL Certificates in DirectAdmin
  2. Request new certificate
  3. Check renewal logs for errors

SSL Not Working on Subdomain

Subdomains need their own certificate or to be included in the main certificate.

ERR_TOO_MANY_REDIRECTS

Redirect loop - check:

  • .htaccess rules
