cloudflared falls back aggressively to HTTP/2 protocol if a connection attempt with QUIC failed. This was done to ensure that machines with UDP egress disabled did not stop clients from connecting to the cloudlfare edge. This PR improves on that experience by having cloudflared remember if a QUIC connection was successful which implies UDP egress works. In this case, cloudflared does not fallback to HTTP/2 and keeps trying to connect to the edge with QUIC. |
