ERR_SPDY_PROTOCOL_ERROR Nginx !!

[shahzaib mushtaq]

Hi,

It was working well back in days but there's sudden error which is
preventing our users to play videos in browser. The error is :

GET
https://domain.com/files/videos/2017/08/01/15015680292fcdf-360.mp4?h=vOilKo_cOUft5fViRqIcMg&ttl=1501588832
net::ERR_SPDY_PROTOCOL_ERROR


We're unable to find any errors in nginx logs.

Here is the Nginx Version :
