chrome :: ERR_SPDY_PROTOCOL_ERROR in chrome

Question

I'm using JS-autocomplete which is working fine in the local environment, but in Live environment, initially autocomplete works properly, but after 3-4 attempts I'm getting net::ERR_SPDY_PROTOCOL_ERROR in the console (only in one page). This is not the case for all pages, other pages have the same autocomplete which is working properly, I have tried in incognito mode and some other browsers, but getting the same error

I have tried following methods

Cleared temp files, cookies, and caches

Flushing SPDY Sockets using chrome://net-internals/#sockets

Updated browser

Flushing DNS and Renewing IP

but these attempts did not solve my problem

Note: I have not installed any Antivirus

Try following two things :-

1. Use http2 protocol for loading your resources as well and for the auto-complete API.

2. Use unique identifier for your auto-complete API(like &t=(new Date()).getTime())
