HTTP/2 is a important step forward for HTTP. The new version of the protocol focused on retaining backward compatability while increasing performance. Thanks to providers like CloudFlare and support from most of the big browsers like Chrome / Safari / IE / Opera (Can I Use), HTTP/2 has become wide spread and a large section of the internet is using it already.

The response returned when using the HTTP2 client was blank, which could indicate a badly configured server or unintended logic by the application when using the new protocol.

How do I fix this ?

Ensure that the HTTP/2 config is correct and that no unexpected behaviour occurs when clients try to connect to the page over HTTP/2
