Customers were discussing issues when using Zscaler and ControlUp together. The remote control feature sometimes does not work until Zscaler is turned off. There were suggestions to check certain ports and GRE tunnels to ensure they are not blocked. It was also shared that Zscaler may be blocking websocket connections. This information will be relayed to the team. URL: https://support.controlup.com/docs/prerequisites-for-controlup-for-physical-endpoints-apps?highlight=websocket

Hello! Are there any customers who are using Zscaler and ControlUp together? Our team is experiencing inconsistencies while using the Remote Control feature on physical endpoints and Zscaler. Sometimes the remote control feature works and other times it does not until we turn off Zscaler completely. Our network team is not seeing any blocks on their end so I’m wondering if there is something else that we are missing that is causing these inconsistencies. When remote control does not work, it shows in the device events that a request was sent. Any help would be appreciated. Thank you!

Check to make sure those ports that Joel suggested are allowed over their GRE tunnels. Within a zscaler environment, there could be multiple GRE tunnels that an endpoint could utilize. It may be blocked on some of them?
the experience with my customer was that zscaler was blocking the websocket connections. This was not evident in zscaler logging but zscaler support did find it after a while.
Thank you! I’ll relay this info over to our team.
