ESXi Host Certificate status alarm while certificate not yet expired !
Actually the expired certificate was not STS signing certificate but host certificate. Solved by renewing host certificates for both hosts. This should be done every 5 years before they expire.
What i have done to fix it :
- In the vSphere Web Client (SSO local admin account), click on vcenter inventory list then click on hosts.
- Select the host showing alarm
- Click the Manage tab and click Settings
- in left menu, under System item, click Certificate.
- Click on the button to renew the certificates.
- Wait while task finish progressing !
I hope that this will help someone else in future 🙂
