SSL Certificate Renewal Issue in On-Premise Setup
We’ve identified an issue affecting SSL certificate renewal in MDM On-Premise deployments, specifically when using Sectigo's new Root (R46). Customers attempting to renew certificates may encounter the error:
"Certificate cannot be added! - Devices are being managed with the existing certificate."
"Certificate cannot be added! - Devices are being managed with the existing certificate."
This issue impacts environments where:
- Renewal is attempted using Sectigo Root R46
- Managed mobile devices are running older OS versions that do not yet trust the new Root
To avoid disruption in device communication, we recommend reviewing the workaround steps and supported builds in our KB article.
