hi,

I am not a vcenter user, so I can’t check here - I think that after reinstalling vcenter you forgot to create a “oneadmin” user in vcenter?

The monitor tries to connect to vcenter, but isn’t allowed, see the message below:

> [@serverx](#):

In the documentation (here: [vCenter Node Installation — OpenNebula 5.4.15 documentation](https://docs.opennebula.org/5.4/deployment/node_installation/vcenter_node_installation.html#permissions-requirement)) you can see what should be allowed for the oneadmin user.
