I have a more reliable way of reproducing the problem.  Finally found a way to get a version of curl that supports http3.  On a machine with docker and Internet connectivity, run this command:

sudo docker run -it --rm ymuski/curl-http3 curl -v https://raspi2.elyograg.org -X POST -d " " --http3

The URL above is on the system where TCP is handled by haproxy 2.4.15 and UDP by 2.6-dev5, a fact that might taint the experiment.  The following test is to a single haproxy 2.6-dev5 instance handling all traffic:

sudo docker run -it --rm ymuski/curl-http3 curl -v https://http3test.elyograg.org -X POST -d " " --http3

Again, if http3 is replaced with http2, the request works.

Thanks,
Shawn
