<div dir="ltr">looks like i have got the issue. Any requests comes from the ip located in geo.conf will be forwarded to a domain whose ip resolve into 110.93.X.X. Now when a request comes from the ip 110.93.X.X , nginx somehow unable to proxy_pass this prefix(110.93.X.X) it to the ip 110.93.X.X and shows the bad gateway error.<br>

The /24 is within the /18. In this instance you want to remove the
/24.<br>
<br>
It might be worth investigating if you've got any others that
overlap. I think you can probably override with a different country
code but using the same makes no sense.<span><font color="#888888"><br>

Now, whenever some ip from the list send request, nginx reply
with gateway timeout :-<br>
<br>
curl -I <a href="http://files.com/files/videos/2014/06/10/14023918368e3411-240.mp4" target="_blank">http://files.com/files/videos/2014/06/10/14023918368e3411-240.mp4</a><br>

In order to resolve this error, i have to manually remove a
network from the file which is <a href="http://110.93.192.0/18" target="_blank">110.93.192.0/18</a> TW;<br>
<br>

<div>What so suspicious with this prefix <a href="http://110.93.192.0/18" target="_blank">110.93.192.0/18</a>
TW ? Why it is causing to crash every other requests ?<br>

What makes you think that this error message is incorrect?<br>
If it's correct and you have a duplicate entry, resolving
the problem<br>
should be pretty simple ...<br>
