IBM MobileFirst 7.1 - /authorization/v1/clients/instance - 404 Not Found - ios

Question

I have developed a MobileFirst 7.1 Hybrid application in eclipse with ipad environment.
This ipad environment is configured with a custom security test that has the following realm:
<customSecurityTest name="myIpadTest">
<test isInternalUserID="true" realm="wl_anonymousUserRealm" />
<test realm="wl_deviceNoProvisioningRealm" isInternalUserID="true" />
</customSecurityTest>
In the application-descriptor.xml
<ipad bundleId="com.xxx.xxx.xxx" securityTest="myIpadTest" version="1.0">
....
</ipad>
This application when installed in the real device works properly with my Eclipse environment and my Staging MobileFirst Server. The Staging MobileFirst Server has HTTP Server Nginx in front of it without SSL.
But when I deploy the same application in the Production MobileFirst Server the device fails to register with the below error logs. This production server has a nginx also in front of it that acts as a reverse proxy to the mobilefirst server and is configured with SSL with a valid CA Issued Certificate. TLSv1.2 with SHA256 Cipher.

I thought the issue was caused by the Reverse proxy so i decided to install the desktopbrowser version in the production but i dont have any 404 issues with the desktopbrowser. The certificate is also trusted by the browser.
Looking forward for your help guys. Thanks in advance.
