SOAP API ON NGINX

I am accessing SOAP API on nginx server, I got the following error.




org.xmlpull.v1.XmlPullParserException: expected: START_TAG Envelope (position:START_TAG <definitions name='ApiController' targetNamespace='urn:ApiControllerwsdl'>@2:351 in java.io.InputStreamReader@8a8e1eb) 



but i can access the same api on Apache server. I am abit lost here and I can’t find anything on nginx and php log.

May I know what could be the problem? I have attached my nginx config file

What’s the difference in XML generated between nginx and Apache?
