We are having problems trying to identify why the WSA is blocking Slack calls. We are seeing the following error...
SyslogAccess: Info: 1510782070.590 0 10.129.X.X TCP_DENIED/407 0 CONNECT tunnel://slack-calls-0f839364977b8qwdsc8.slack-core.com:443/ - NONE/- - OTHER-NONE-DefaultGroup-NONE-NONE-NONE-NONE <-,-,-,"-",-,-,-,-,"-",-,-,-,"-",-,-,"-","-",-,-,-,-,"-","-","-","-","-","-",0.00,0,-,"-","-",-,"-",-,-,"-","-",-,-,"-"> - NONE, "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) AtomShell/2.8.2 Chrome/56.0.2924.87 AtomShell/1.6.15 Safari/537.36 Slack_SSB/2.8.2 Slack_SSB/2.8.2 Slack_SSB/2.8.2"

My first question is whether anyone knows the definitions of the fields in the WSA log format?
My 2nd question is what is causing this to be denied? This site is explicitly allowed and works for other users.
