Issue/Introduction

How to resolve alert "A server certificate on your system is soon expiring or has expired already."?

Environment

• EDR Server: 6.4.0 and above

Cause

• The legacy self-signed cert is not validated for expiration.
• Sensors are assigned to expiring or expired certificate.

Resolution

• The legacy self-signed cert is not validated for expiration, so it will continue to work as expected regardless of the expired status (as long as it continues to use the "standard validation" setting). 
• Assign any sensors to non expiring or valid certificate.
