We've identified some problems with HTTP/3, where requests would sometimes stall instead of returning the expected result. As a quick workaround #381 removes the upgrade Headers, so clients will stick with HTTP2 while still being able to investigate HTTP3 by forcing the upgrade, but we need http3 to be re-enabled. The failing requests could be reproduced in curl and firefox (probably also chrome, but there it's more complicated - albeit documented in the README - to force http3 with certificate). In the following I've added some output from opendigitizer-service using http3 and -DOPENCMW_DEBUG_HTTP=ON cmake option and curl as a client:

We've identified some problems with HTTP/3, where requests would sometimes stall instead of returning the expected result. As a quick workaround #381 removes the upgrade Headers, so clients will stick with HTTP2 while still being able to investigate HTTP3 by forcing the upgrade, but we need http3 to be re-enabled. The failing requests could be reproduced in curl and firefox (probably also chrome, but there it's more complicated - albeit documented in the README - to force http3 with certificate). In the following I've added some output from opendigitizer-service using http3 and
-DOPENCMW_DEBUG_HTTP=ONcmake option and curl as a client:To test in firefox, set in
