Hi! HTTP/2 requests OpenSSL 1.0.2. HTTP/2 is enabled for Apache since its 2.4.17 version. My server runs on Centos 6.9, Apache 2.4.25 and EA4 under SSL 1.0.1e. Seems like SSL 1.0.2 cannot be installed in Centos 6.9? How to solve this SSL version issue in order to install HTTP/2? Any advice is welcome.

  HI, You won't need an updated OpenSSL version to use our version of HTTP2. We've statically built the SSL modules so they don't require an installed OpenSSL library to use the HTTP2 functions. You should be able to install this now.

  Jacob, many thanks. Is there any risk/history of HTTP/2 breaking Wordpress websites asfar as you know?

  HTTP2 is enabled following the steps here (Best Answer) EasyApache 4 HTTP2 Support However, KeyCDN reports the website is not under HTTP2, screenshot here diigo.com/item/image/5pj5q/x6qr and Akamai tells me my browser does not support HTTP2 diigo.com/item/image/5pj5q/5is0 However, I use Chrome Version 57.0.2987.133 (64-bit) - last version. Chrome is supposed to work with HTTP2 since end last year. Please, any ideas on how to solve this ALPN issue?

  Hello @itmonitor, Could you check to see which MPM is enabled on your system?
  rpm -qa|grep mpm
  It's possible your system is using MPM ITK, which isn't compatible with HTTP2. Thank you.

  Michael I had requested my hosting company to enable HTTP2. On checking the steps they took, I found out they forgot to add the .conf file. For this reason HTTP2 was not loading. I added the file and it is loading now. Many thanks, IM
