Answer 1

Is it Chrome?

Chrome has dropped support for NPN in recent updates. If you want to continue to support HTTP/2 on Chrome, you need to install the latest 1.0.2 version of OpenSSL and recompile Nginx with 1.0.2 OpenSSL.

Reference:

1. Roll back to HTTP/1.1 in the new version of Chrome

2. Supporting HTTP/2 for Google Chrome Users
