Web browsers only use HTTP/2 over HTTPS, and use ALPN to determine if a
server supports HTTP/2. If this option is enabled, web browsers can use
HTTP/2 to communicate with the server. However web browsers are stricter
with security when using HTTP/2, at a minimum you will need to add the CA
certificate used to sign the server certificate into your web browser's
trusted authorities. Otherwise the connection can fail with a security
error, without giving an option to ignore this and proceed anyway.
