Well it works for us now with the header stripped, but we don't know what's causing it, just that it's not our problem

It does not, the configuration is valid. Simply setting server protocols to h1 h2 isn't enough to stop this from happening, we had that set before the issue was resolved. header -Alt-Svc seems to be necessary.

Disabling the Alt-Svc header on that specific resource fixes the issue

Caddy supports HTTP/3 and I think it announces it, although the underlying proxied application might not, as is the case for our back-end, as Tonic only does HTTP/2

Running Kestrel locally is OK, so is running the server locally when a direct connection can be made (localhost:xxxx)

Repro is difficult, we seem to have traced the issue to some bad interaction between the Caddy proxy server and the Windows implementation of HttpClient
