I deploy my project with app engine , then configure my own load balancer and enable quic .

But when I send request, it only support h3-Q050,h3-Q046,h3-Q043, not support h3-29=":443" (ietf).

How can I make it support h3-29?

Hi,

Currently those are the only supported versions of QUIC in GCP HTTP(S) Load Balancers, and any other version of QUIC should make the connection fall back to HTTPS or HTTP/2 instead of negotiating QUIC.

I have used the google cloud platform HTTP(S) Load Balancers and enable quic. Is there anything wrong?

Or the google cloud platform is not supported for h3-29 (IETF） by now ?

Hello, as mentioned by my colleague before the supported version of QUIC are h3-Q050,h3-Q046,h3-Q043. I have done some research on this, and have found that this version [h3-29] of QUIC is currently deprecated
