Cloud App Security - Continuous Log Issue

[Meg Simmons]

In the Cloud App Security portal I have followed the Instructions provided in this Microsoft Doc to configure continuous logs to be sent from my SonicWALL (syslog) to my Log Collector.  The log collector shows 'Connected' but is not receiving data. (See attached screenshot)

I have triple checked my settings in the SonicWALL and my Ubuntu server. 

I can confirm logs are flowing from the SonicWALL to the Ubuntu server but, how can I check if they are reaching the Cloud App Security portal?  

Note: we do not block outbound traffic

In the script provided for configuring the log collector, one specific line caught my eye. "SYSLOG=false". If I'm using syslog instead of ftp, would I change this to "true"?
