Netbox Proxbox Plugin

[TheDmDLP]

I am trying to set up the Proxbox plugin and always fail at the connection between netbox and proxmox.
I am running a 4 node cluster and would like to have all the info of the VM's and containers documented in Netbox. I have entered a node in the config. It is not quite clear to me whether I have to enter all 4 nodes in the config or whether one is enough. I have created an API key and given it the right to read in proxmox.
However, when I click on Proxmox full update under plugins, the error message appears:
The request failed with code 403 Forbidden: {'detail': 'You do not have permission to perform this action.'}.
I don't want to give the Netbox user write permissions in Proxmox for security reasons.
Thx 4 your Help
