Running an HTTPS status check is straightforward: use tools like curl or online checkers to verify your site's SSL certificate and response codes. For common issues like mixed content errors, fix by ensuring all resources load over HTTPS, and for expired certificates, renew them promptly with your provider. Redirects from HTTP to HTTPS should be 301s, not 302s, to maintain SEO. If you see warnings, inspect your certificate chain—missing intermediates are a frequent culprit.
