Failure when attempting to connect to Endpoint Manager database.
Last Updated September 17, 2018
When trying to connect to the Symantec Endpoint Protection Manager (SEPM) database within Advanced Threat Protection (ATP), you receive a connection Error.
ATP User Interface (UI) will show "connection error" under the Settings -> Global Settings -> Synapse.
Windows Application log will show:
Event ID: 17835 Logon
Encryption is required to connect to this server but the client library does not support encryption; the connection has been closed. Please upgrade your client library. [CLIENT: <ATP IP>]
This issue may be due to encryption being enable on the Microsoft SQL database in which the SEPM connects. At this time, ATP does not have a UI checkbox option to accept encrypted communication between ATP and SEPM SQL database server.
