I proceeded with your instructions. But it still doesn't work.
**this node deploy by using ansible on oracle linux 8.6

Update to 5.2.0 still having the same issue.

Hi there,

I found that there are no "requests" directory in /opt/vprotect/.vmware/ even after I created a new one and restarted the vprotect-vmware service. It still doesn't work as expected.

Here is the result of vprotect-vmware status. Is there anything wrong with it?

Thank you for your attention and cooperation.

Is there a solution?
