Issue

• When I configured my LDAP/AD server on CJOC, it said that it is not possible to resolve the DNS name of the host.
• When I access to a worker with dna connect worker-1 and try to resolve a DNS name with dig google.com it is not possible to get the IP of the host.

Environment

• CloudBees Jenkins Enterprise (CJE)
• Amazon Web Services (AWS)

Resolution

If you are using a custom VPC for your CJE cluster check that you have configured a DNS server on your DHCP, for more details take a look at the Amazon documentation Creating a DHCP Options Set
