Hello Guys,

We recently upgraded Nginx from nginx/1.9.12 - nginx/1.13.2, details of nginx/1.13.2 supported modules are given below. We are facing problem of automatic enabling of HTTP2 protocol on bsa1.example.com as we only enabled http2 on dsa1.example.com. Nginx configurations of both sites are given below.

Supported urls of different Nginx configurations are given below respectively
1 - https://dsa1.example.com/forums/user_avatar/www.example.com/cooltahir/25/1497380_1.png
2 - https://bsa1.example.com/blog/wp-content/plugins/ultimate-responsive-image-slider/css/slider-pro.css?ver=4.6.1


Site to verify Http2 protocol
