Issue

After setting up a new Cisco Umbrella Secure Internet/Web Gateway in the environment the VMware Carbon Black EDR sensor stopped reporting in.

After implementing the new secure gateway, the customer needs to add the IP addresses and ports from https://go.my.redcanary.co/account/help "Important Addresses" section. Adding these exclusions will allow full connectivity to the Carbon Black server from the sensor.
