Applies to

  • ONTAP System Manager 
  • ONTAP 9
  • Self-signed certificate

Answer

It is expected that the browser displays the following warnings for the HTTPS certificate until a Certificate of Authority (CA) signed certificate is installed within ONTAP.

  • Not Secure
  • Certificate is not valid

This is explained in the documentation Use System Manager to access a cluster as well.

Note: Browsers will report self-signed certificates as Not Secure. This is not specific to Ontap or System Manager.
