Hi Shawn, First, thank you for your interest for QUIC in haproxy :) I have quickly tested POST on my side but did not see any issue. To help you diagnostic your problem, you can try to activate the traces on the stats socket. for the transport traces : $ trace quic sink buf0; trace quic level developer; trace quic verbosity clean; trace quic start now and for the mux : $ trace qmux sink buf0; trace qmux level developer; trace qmux verbosity minimal; trace qmux start now then you can display the traces with the following command : $ show events buf0 For the h3 layer, the trace mechanism is not currently implemented. You should instead recompile your haproxy binary with the DEBUG options : -DDEBUG_H3 -DDEBUG_QPACK and watch for the stderr output for your process. Thanks again for your help, Regards, -- Amaury Denoyelle
