I am unable to check for software updates within the PI 3.0 interface through our internet proxy. The page displays the error "There was a problem connecting to cisco.com from the Prime Infrastructure Server". I have valid proxy settings, and the Test Connectivity button within the Administration / Settings / System Settings > (General) Support Request results in three Successful tests. Seems like an obvious recurrence of CSCum37804, but 3.0 is not mentioned in the bug report. Is anyone else having this problem?
