Netflix, what fix?

Hello all...

I'd like to start by saying that I know that this question has been asked time, and time again. I have searched the forum at length and attempted many of the suggested solutions to the problem.  The problem being:

Why, oh why, can I not get Netflix to work on my Roku 3 behind the UTM?  
(Edit: Slacker Radio is another more popular service that also no longer works now.)

In fact, most streaming apps on the Roku ar no longer able to retrieve content. 

I have tried adding the devices to the skip list - fail

I have tried adding regex to the exceptions list - fail (Most solutions offered were variations of regex forms)

I have disabled WebFilter, IPS, ATD, and created the ANY>ALL>ANY firewall rule t open it wide up. No dice. 

I am hoping that there is someone here that has an answer to this question. I had found a post of about a week ago or so that claimed to have resolved the issue, alas to no avail. 

Some minimal logging I am able to get:
