Hi,

I just try to upgrade Virtual Appliance console from 6.5.417.0 to 7, following the ESET Online Help :
https://help.eset.com/esmc_deploy_va/70/en-US/deployent_on_vsphere_esxi.html?va_upgrade_migrate.html

But I get the 3 following errors... :

- Received server certificate is not valid. Please check whether server contains valid peer....
- Reading previous installation settings... failure
- Received server certificate is not valid. Please check whether server contains valid peer certificats

 

Thanks in advance for you help
