How to search for facebook solutions?

Question

Hi folks, 
 I am trying to fix my access to facebook. If I disable the webproxy, facebook works. 
 With the webproxy enabled and https scanning disabled facebook doesn't work. I have re-enabled the https proxy scanning and set a bypass in the profile. Sometimes the FF throws up an insecurity error and will not let facebook through. I look at the logs and see the facebook is blocked because the connection timed out. 
 I don't have a PC to try this out on, all being done on Mac books or ipads. 
 This is getting very frustrating. 
 Currently running UTM 9.5b, but this problem started before I loaded 9.5b onto the UTM.

Removing HTTPS scanning was the easy and wrong answer. 
 I reviewed the daily reports and found very little facebook activity and lots of fbcdn.net. 
 So I changed all the htpps bypass back to active and setup a new set of exceptions which work except for facebook messenger, something else to investigate. 
 The exceptions I added are 
 ^https?://[A-Za-z0-9.-]*\.facebook\.net 
 ^https?://[A-Za-z0-9.-]*\.facebook\.com 
 ^https?://[A-Za-z0-9.-]*\.fbcdn\.net 
 This works and has increased my security on websurfing. Google on FF on mac book pro is slower to respond and google on android is broken. Needs new certificate installed.
