If the ephemeral nodes are marked down, but the FQDN (template) nodes are marked as up in the pool, this means that the F5 CAN resolve DNS, but the health monitor check is failing.

You can test the health check monitor by sending a cURL request from the F5 bash prompt:

curl http:///gen/1/admin/node/status
