I want to decrypt Dropbox but it doesn't work. I have a catch-all decrypt policy that decrypts any-any SSL. It works fine except for Dropbox. My understanding is that Dropbox is on the PanOS internal exception list so decryption is supposed to be disabled automatically for DB. Looking at my traffic logs, I can confirm that application dropbox is not decrypted. However, my Dropbox client still reports it's unable to establish a secure connection.
Is there anything I need to do to make it work?
