We are running into issues attaching baselines in the VUM. We get the following error. Some details:
Host cannot download files from VMware vSphere Update Manager patch store. Check the network connectivity and firewall setup, and check esxupdate logs for details. The log file reflects: [Errno 4] IOError: <urlopen error [Errno -3] Temporary failure in name resolution>'
I was able to confirm domain name resolution to rule that out...kind of. The IP resolves every time, but the FQDN results in the error, "Temporary failure in name resolution." I checked the VUM Home > Admin > network settings to confirm that both the FQDN and the IP were configured, and that there were no misspellings or fat-fingering.
Of note, we already have the baselines. But when we click "Stage" or "Remediate" it fails with the above errors.
