sutter,
view can be set to http
example config
Configure Each View Connection Server for HTTP Traffic

I tried above in older view versions, (at the time it was about getting better performance from the brokers)
so two choices here, stick with mode tcp and let all traffic be encrypted, or disable https at the brokers so you can use mode http.
