Hi Richard
Thanks for reply!
Actually Its working without proxy, but we have requirement that proxy to be used and all external URIs in use for the app will be whitelisted.

I have white listed URLs mentioned in the following link but this is not resolving the issue. am I missing some URL to be whitelisted ?

This may require you to check your organization firewall network. Is your whitelist set on the firewall of the device or the firewall of the proxy network?
