Opening handshake failed. QUIC_TLS_CERTIFICATE_UNKNOWN

[wanjohiryan]

Error:

I keep getting 'Opening handshake failed' in brave v1.46.144 (running on chromium v108.0.5359.128) and chrome canary v111.0.5494.0

I have tried searching all over the internet but nothing seems to solve this.

This includes:

1. Generating new certificates,
2. allowing insecureOrigins in tls.Config
3. Using a different machine

Probable cause

Chrome /Chromium seems to have dropped support for the flag --ignore-certificate-errors-spki-list

Expected behaviour

Run warp in the browser without TLS_CERTIFICATE error

After a lot of tinkering, a found a working solution:

chrome --origin-to-force-quic-on=localhost:4443 localhost:4444

Works like a charm.

Also, a simpler way to create self signed certificates would be with mkcert

mkcert -install
mkcert localhost

The fingerprint is not required after they dropped support for the flag --ignore-certificate-errors-spki-list

Closing this issue.
