SSL Connection to target failed - Certificate retrieval failed:Name Resolution (DNS Lookup) failed

mthomas3 — Thu, 31 Aug 2023 18:29:48 GMT

I was able to run the healthcheck on our vcenter server 2023-08-22T20:36:11 successfuly but on 2023-08-31T16:12:01 it failed. Does anyone know why it would suddenly fail the dns resolution? No changes were made to the dns entry for skyline.

resolved the network issue by creating the file touch /etc/systemd/network/10-eth0.network.manual and providing permissions.
