at the ESXi-Hosts in one vsphere Clusters I got an Error when I do a "Compliance Check".
I have only attached the predfined Baselines.
My vCenter Server Appliance is on version 7.0.1.00300 and the ESXi Hosts are on ESXi 7.0.1 Build 16850804 .
In the VUM Log I got the following Error:
<errorDesc>Failed to download metadata.</errorDesc>
<msg>('http://URL-to-vCenter:9084/vum/repository/hostupdate/CIS/CIS-ESXi-7.0-Addon-cumulative_metadata.zip', '/tmp/tmp9ri_3blh', '<urlopen error [Errno -3] Temporary failure in name resolution>')</msg>
I have already checked if the ESXi-Hosts can connect to vCenter via Port 9084. The ESXi-Hosts can connect to the VCSA via Port 9084.
Does anyone have any idea how I could solve the problem?
Thank you in advance for your support.

Issue appears to be with name resolution somewhere as per the snippet .
Disable the firewall for the host and try once
Also reset vum database can be helpful
