When opening the Veeam Backup & Replication console youare presented with the error “Failed to check certificate expiration date”.
This is due to Veeam having an old certificate in its cache. You will need to generate a new certificate.
If the certificate used is self-signed (which they are by default) then you can generate a new certificate from within the Backup & Replication console. Note that this will restart the Veeam Backup Service.
- Go to general options, security tab and click install.
- In the wizard select “generate new certificate”
- Follow the wizard through.
