Hello guys,

My https site cannot be displayed in Safari with "nsposixerrordomain:100" error. I'm running nginx 1.13.3 and Ubuntu 17.04. The site is displayed fine in other browsers and the SSL test also completes fine (A+). When I disable the http2 from server block, it displays fine in Safari.

Thanks for any useful info.
