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.
