curl: quiche_conn_recv() == -10

[bagder]

When I build curl with the current quiche code (git master commit a90de02) (with ./configure --with-quiche=[src] in the curl tree, using current curl git master) on 64 bit Debian Linux and run it like this:

./src/curl --http3-direct https://quic.tech:8443 -v

it ends up getting -10 (QUICHE_ERR_TLS_FAIL) returned from the quiche_conn_recv() function.

I don't understand why and would need some help on how to diagnose and get further on this. Can I get more debug info or logging somehow to better understand the details of this failure?

Am I using the wrong end point for my test?

https://quic.tech:8443 is talking h3-20, which should align with the commit you pint at.

Are you setting the ALPN ID to the correct value with quiche_config_set_application_protos()?

https://github.com/curl/curl/blob/3af0e76d1e71995b7790c74e79b76af86ee7c681/lib/vquic/quiche.c#L73 suggests you are trying to talk hq-20. For H3, you can do something like

quiche_config_set_application_protos(qs->cfg,
        (uint8_t *) QUICHE_H3_APPLICATION_PROTOCOL,
        sizeof(QUICHE_H3_APPLICATION_PROTOCOL) - 1);

Thanks, that was indeed the problem.
