Question HTTP/2 Enabled But Request Protocol HTTP/1.1

Hi can you check these requirements?

Known Issues and Limitations
openssl 1.0.1 or higher is required to work with modern ciphers necessary for HTTP/2. For several older Operating Systems (such as CentOS-5 and RHEL-5), earlier openssl version is provided by the OS vendor.

HTTP/2 support on such OSes may be unavailable.

It is serverwide option, so there is no way to configure it on per-domain basis.

Also please check KB with troubleshooting materials: #213942145
 
I think you are all set.

You have to use http2 enable browser to receive http2 requests.

Also you can set file such as jpg,gif,txt server directly by nginx so the nginx will serve the in http2. This setting is in hosting options.

Also please note http2 support request only with SSL enable.

Are you looking at the nginx ssl access log? Also they to use different browsers.

You can try the online http2 test metion before than see if its appear as a http2 access in the log file
 
his domain is not showing http2 if we open in browser too. i checked it with firefox extension.

kindly remove all data from
Additional nginx directives and try again
