Issue:
After issuing a compliance check on the Update tab, the response from vSphere is:
Host cannot download files from VMware vSphere Update Manager patch store

1. SSH into the host OS:
$ ssh root@esxhost.mindwatering.net
<enter password>

2. Verify that the host can reach the Update port on the vSphere appliance:
[root@esxhost:~] nc -z 10.10.0.20 9084
Connection to 10.10.0.20 9084 port [tcp/*] succeeded!

3. Do one of the following:
- If the connection fails:
Either the update service is down or there is a firewall blocking the port. Verify on a neighboring host to be sure.

- If the connection succeeds, this is likely a DNS failure.
Use the nslookup command to confirm forward and reverse DNS. If this occurs during a time when the internal DNS is not working, then we can compensate by adding a host entry.
Note that your update will very likely be overwritten on future updates (hence the warning at the top).

[root@esxhost:~] vi /etc/hosts
# Do not modify this file directly, please use esxcli.
127.0.0.1 localhost.localdomain localhost
::1 localhost.localdomain localhost
10.10.10.100 esxhost.mindwatering.net esxhost
10.10.0.20 vcsa.mindwatering.net vcsa
