I looked into your chats and found that you were facing issues in creating vps when you moved to Proxmox Virtualizor and used a webuzo template where perform operation option was not selected.
Re-adding the template on panel with that option selected would solved vps creation issues.
For HAproxy issues, I was not able to access your panel to check its config.
Can you please update access details in ticket ?
Before moving to Proxmox Virtualizor from KVM Virtualizor, I believe everything was working as expected.
We are awaiting a response with access details so that we can help you out.
