            at ro.sync.exml.Oxygen.main(Unknown Source)

And because of this the actual host to which the user needs to connect is unknown

(Custom Code)

Code: Select all

 Could not connect to <host URL>

            at com.o2.utils.HttpClientFactory.executeRequest 

And

Code: Select all

java.net.UnknownHostException: <host URL>

Please can you help so that the customer is able to use proxy server http://proxyconfig.xyz.corp/proxy.pac and Validate and connect to the Host URL

Hi,

If you start Oxygen, then go to the Preferences->"Network Connection Settings / Trusted Hosts" page and add "proxyconfig.xyz.corp" to the trusted hosts list, then re-start Oxygen, do things start working?
