I’ve got a Netgear Wireless router (R6900P) and Zscaler on my work lappie. The router uses Disney Circle to filter websites for my teenager, but also blocks all internet traffic to my work laptop when Zscaler is turned on. Turning off either Disney Circle or Zscaler allows for internet traffic. I’m working around this issue by turning off Disney Circle and then turning it back on----my lappie will then not get blocked. No other computers (~5) we’re using at home have this issue; but none have Zscaler either.
