问题
That error message logged to the chrome console from a long-pending request after around 15 minutes.
It looks client-side error because server processing still worked.
I did not find any article related to this error message.
can any buddy let me know how to solve this issue?

According to the chromium source I think it means that a spdy ping timed out.
...
{net::ERR_EMPTY_RESPONSE, "http.response.empty"},
{net::ERR_HTTP2_PING_FAILED, "spdy.ping_failed"},
{net::ERR_HTTP2_PROTOCOL_ERROR, "spdy.protocol"},
...

Chrome sends such pings before and after a request.
