</div></div>You may want to try 1.7.4 to see if it helps (there are some<br>
potentially related changes in nginx 1.7.3).<br>
<br>
If it doesn't, providing debug log may be helpful.  See<br>
<a href="http://wiki.nginx.org/Debugging" target="_blank">http://wiki.nginx.org/Debugging</a> for more hints.<br>
