Summary
Problem
On macOS 26.5.2 arm64 with Freelens 1.10.3 and Electron 41.10.0, navigation to the loopback HTTPS renderer could remain in Chromium's
CERT_VERIFIER_JOBfor 30 seconds and then fail withnet::ERR_TIMED_OUT. Electron's JavaScript certificate verifier was not reached because the platform certificate verifier stalled first.Fix
The renderer proxy already generates an ephemeral certificate for each application process. This change calculates the certificate public key's SHA-256 SPKI fingerprint and passes that exact value through Chromium's
ignore-certificate-errors-spki-listswitch before Electron becomes ready.The exception is limited to the ephemeral public key used by the local renderer proxy. It does not disable certificate validation globally or trust a hostname independently of that key.
