Which port uses CA Service Management Mobile?
80 - IIS?
8080 - Tomcat?
Which??
Default SDM REST Port that the mobile app depends on, is 8050.
Actually, that's not entirely complete.
For downloading the attachments on a ticket, the Mobile App uses the (default) SDM Tomcat port (8080), just like the web clients.
Download CA Service Management APP Google Play (Android) & Itunes (IOS-Iphone)
and 8050 be the OOB REST port that I hope you have modified to SSL like 6443 or any others..
