Mobile App not working

Hello,

The Mobile app is not working with our Cyclos PRO installation. When the Android app is installed and the Cyclos location is completed as, all that is displayed is a blank screen with an empty alert box. We are never offered a place to log in. Would you help identify the problem?We have updated the DNS so that now http://our.domain.com pulls up the Cyclos start-up page. The "Main URL" field in the default configuration also says our.We have enabled the 'Web Services' channel in the default configuration, the Groups configuration, the User, and for the Accounts.What else do we need to do to make it workDo we need to do anything else to the configuration?Do we need to change anything in Tomcat or the server installation?Do we need SSL?

Please help.

I didn't find the right solution from the Internet.
