I’m unable to access a local go-quic server using a either firefox or chrome on ubuntu amd86.

However, if I run the server on, for instance, port 4433 – having already added a root certificate to /usr/local/share/ca-certificates for localhost, and created a signed key/cert for the server – curl can access the server (curl -v –http3 https://localhost:4433).

Enabling the port on the firewall, gufw, to allow 4433 makes no difference. Same applies to purging the browser history.

Firefox version: 129.0.1. Chrome version: 127.0.6533.119.

I just can’t think of anything else to try out – very grateful for any suggestions on moving forward!
