Veeam self-signed certificates issue

veeam-self-signed-certificates-issue-01

Veeam reported a bug related to self-signed certificates generated during the installation of the software and used by the backup infrastructure components to communicate safely.

By default the generated self-signed certificate is created and set to expire after one year and due to a bug after the Update 3 installation date, a strange behavior occurs while opening the Veeam Backup console.

The problem arises when you open the Veeam Backup console after 11 months after Update 3 installation time. You receive a Failed to check certificate expiration date error message and, if the message is ignored, after 12 months the Veeam functionality breaks and the agent management functionality and all granular restores fail.
