Hello,
Thank you for your message.
I see only some SSL 2.0 connections and lots of unencrypted TCP traffic at all, when remote clients connect to the RU.
All traffic between Viewer and Host uses end-to-end encryption. So the traffic between Viewer <-> Server, and Host <->Server is not encrypted because it has already been encrypted. What you possibly see as the "unencrypted TCP traffic" has in fact been encrypted already.
Hope that helps.
