problem in config Nginx with SMP 3

Hi All,

          I had configured Nginx with SMP 3 but getting error while doing sync from agentry server..

     Steps given below:

1) Installed Nginx in DMZ and have configured the configuration file as described in the document

    2) Have created a self signed certificate for Nginx server and installed it in smp keystore.

    3) In Nginx config file the upstream backend we have put the url of the agentry application i.e (<smp server ip>:8081)

    4) After all the configurations we are able get hit the https port of the smp server via Ngix server (<nginx server>) and able to get the message  "i am here" from the browser .

but getting blank result on URL (<nginx server>:<configured port>/SAPWM)

     5)while doing sync on agentry client using URL (<nginx server>) getting error:

Logging user into server

   Logged in

Sending client info

Unexpected disconnection from server (11)

Connection failed

Ending transmission

Kindly advise..

Thanks
