HTTP/2 stream 1 was not closed cleanly: INTERNAL_ERROR (err 2)

is it an error or a normal output?

That’s a problem with your ssl configuration. That’s not the blocker doing that.

[simonjoom]

ok
But i think it's due from http/2
nghttp2/nghttp2#746

did you test your code using http/2 instead http/1 with ssl?

For the record, sending Content-Length: 0 with 204 status code is a violation against RFC 7230 (See https://tools.ietf.org/html/rfc7230#section-3.3.2). We implemented this in nghttp2 v1.17.0. But user reported that some widely used service sends Content-Length:0 with 204 code (#735).
We workaround this by simply discarding such header field in upcoming nghttp2 v1.18.0.
