SSL certificate setup and troubleshooting

Set up or troubleshoot the certificate and HTTPS path when a website shows security warnings, redirect loops, coverage gaps, or renewal problems.

When it fits

Use this when a domain or subdomain is not covered, the browser reports an invalid certificate, HTTPS redirects loop, mixed content remains, or a provider change has broken renewal.

What it includes

  • Review of hostnames, DNS, provider settings, certificate coverage, and chain details
  • Setup or correction of provider-managed certificate and renewal settings
  • HTTPS and redirect checks across the intended domain variants
  • Identification of mixed-content resources and stale HTTP links
  • Browser and command-line verification after the change

How it works

  • Reproduce the warning and identify whether DNS, hosting, proxy, or certificate settings cause it
  • Correct the smallest relevant part of the SSL and HTTPS path
  • Recheck certificate coverage, redirects, public pages, and renewal ownership

Expected result

A valid and documented HTTPS setup for the intended hostnames, without avoidable certificate warnings or redirect conflicts.
