2 years ago Thanks Peter. I dug into this, and haven't been able to find any issue with the s2n-quic server itself. I've opened an issue to hyperium/h3, which is the HTTP/3 implementation we use for this interop test.
Problem:
The HTTP3 interop (https://interop.seemann.io/) test with Kwik client fails. See for example https://interop.seemann.io/logs/2022-08-18T00:39/s2n-quic_kwik/http3/
Solution:
I analysed an earlier instance of this error (https://interop.seemann.io/logs/2022-08-17T08:08/s2n-quic_kwik/http3/server/logs.txt), and it's clear the handshake succeeds and also server seems to receive the stream frames containing the HTTP requests, given these log statements:

However, server does not send stream frames for the HTTP request streams (4, 8, 12).
