[CentOS] ALPN and Http/2, CentOS 7.4
Now that 7.4 CR has delivered OpenSSL 1.0.2, I should be able to serve http/2 pages to Chrome, but I still see messages that ALPN is not enabled. OpenSSL 1.0.2 is installed: $ rpm -qa |grep openssl openssl-libs-1.0.2k-8.el7.x86_64 openssl-1.0.2k-8.el7.x86_64 But https://tools.keycdn.com/http2-test says "www.stevenstern.me" supports http 2 but ALPN is not supported.
