The Pi’s low power draw and cheap price make it a go‑to for hosting tiny web services, internal dashboards, or a personal API gateway. Throw TLS in there and you get confidentiality and integrity, but one small mis‑configuration can make every HTTPS request hang until the client gives up.</p> <p>The usual culprit is the dance between <strong>SNI</strong>, <strong>OpenSSL’s default cipher selection</strong>, and the Pi’s limited CPU. Below I’ll walk through why this happens, how to spot it, and the practical tweaks that keep the Pi from blowing up the handshake.</p>
