Server still accepts a deprecated TLS version
Your server still completes connections over {listed}.
Why it matters
Your server still completes connections over {listed}. These versions were formally deprecated (RFC 8996) because of weaknesses that modern versions fixed, and keeping them enabled allows a network attacker to force a client down onto the weaker protocol rather than the strong one it would otherwise negotiate. Current browsers already refuse them, so disabling these breaks nothing your real users depend on — and leaving them on is a common compliance failure (PCI DSS in particular).
How ShipReady detects it
TLS configuration checks. The only check that inspects the transport itself rather than an HTTP response, so it opens its own TLS connections instead of using the shared PageContext. Both probes are passive: a TLS handshake exchanges no application data, sends no request, and changes nothing on the server. Certificate expiry is the highest-value item here — an expired certificate takes a site completely offline for every visitor, and it is entirely preventable with notice.
Detection is deterministic. ShipReady reports this only when it observes the condition directly, and prefers to miss a real problem over inventing one. Rule version 1.0.0.
How to fix it
This is the prompt ShipReady puts in your report — written to be pasted straight into Cursor, Claude Code, or whichever assistant built the app.
Your server still accepts {versions}, which are deprecated (RFC 8996) and enable downgrade attacks. Require TLS 1.2 or higher: nginx `ssl_protocols TLSv1.2 TLSv1.3;`, Apache `SSLProtocol -all +TLSv1.2 +TLSv1.3`, or your CDN/load balancer's minimum TLS setting (Cloudflare: SSL/TLS -> Edge Certificates -> Minimum TLS Version). Current browsers already refuse these versions, so disabling them will not break real users.Frequently asked questions
