Description
ServiceNow instances have updated to allow only TLS 1.2 and SCOM is not able to communicate with ServiceNow anymore.
Release or Environment
All ServiceNow instances
Cause
ServiceNow instances have been migrated to support only incoming traffic from TLS 1.2 as the use of TLS 1.2 is a recommended security best practice that provides a higher degree of privacy and data integrity over previous versions and to maintain compliance with NIST 800-53.
