SSL Certificates

This tag covers SSL/HTTPS setup and troubleshooting as it specifically affects PostRSS's ability to reliably sync a website's RSS feed. It explains why an expired, misconfigured, or self-signed SSL certificate can silently break automated feed syncing, since automated systems tend to reject insecure connections outright rather than showing a warning a human visitor might click through. Articles here cover a practical SSL health checklist — verifying certificate validity, checking for mixed-content warnings, and confirming your feed URL itself loads without a browser warning — plus guidance on setting up free, auto-renewing certificates through Let's Encrypt for self-hosted sites. This tag is technical and troubleshooting-focused, aimed at readers whose feed sync has unexpectedly stopped working. Check this tag first if automation that previously worked has suddenly gone quiet.
