We are also experiencing this same issue, we're using Proxmox 5.1, we're using pre-built Virtualizor templates (also tried custom - e.g. CloudLinux QEMU).

If we create the directory (i.e. /var/lib/vz/images/1002), we no longer get the error "QEMU : File Convert Error There was an error in creating the VPS. Click here to reinstall the Virtual Server", but instead get an error relating to change root password "There was an error in setting the Root Password of the VPS ".

We tried to create a Lets Encrypt SSL, which also seems to fail.

also posted a ticket #551953.

Hi,

Can you please make sure you have placed correct hostname and password in slave settings on panel ?
If it still gives the same error, then please open a support ticket so that we can check and help you out.
