After configuring the SEP Policies in Advanced Threat Protection (ATP) Platform, proxy and submissions settings in the External Communications policy on the Endpoint Protection Manager (SEPM) are reset to default values.
If clients need to connect to ATP through a proxy, this will result in multiple clients showing "Authentication Pending" status under Enrollment Statistics indefinitely.
- In the network design for this environment, the Endpoint Protection (SEP) clients may need to use a proxy to communicate with ATP Platform management server or ATP Platform All-In-One.
ATP currently utilizes the PUT method to update the Private Cloud settings through the SEPM's REST API. This will overwrite the existing External Communications policy with the configured settings. Utilizing the PATCH method will edit the existing policy with the new settings.
