We have recently upgraded an MX200 from TC7.3.6.ea51021 to CE 9.2.3 3ba381b, since the upgrade the endpoint is showing a warning regarding a Certificate Expiry : A certificate has expired 17584 days ago. Please, update. I am not aware of any certificates that would need updating. The endpoint appears to be functioning as expected.
Yes, it is a known defect and the bug-ID is : CSCvg46418
Workaround :This diagnostic warning is cosmetic only and may be ignored. The default self-signed certificate is valid for 20 years so any endpoint that is manufactured or factory reset after January 1, 2018 will show this incorrect diagnostic.
Fix : This issue has been resolved in latest firmware CE 9.2.4 (and beyond).
As CE 9.2.4 is deferred, you can download CE 9.2.5 from here for SX20, MX200/300G2 :
