I have stripped Down To minimum functions (removed SSL and all) but still I am getting the 404 rerror.

But I have tested again & again and found out that the three lines near end.

if ($http_accept_encoding ~ gzip) {
   set $w3tc_enc _gzip;
}

those above three line when removed or commented out then I am not getting that error.
But maybe It will block some functionality of my site too.
So I want to know the solution of it.
