ERF12-7947 - Unable to retrieve DHCP subnet

Generic or SSL connection errors

Please see Proxy_communication_errors first for SSL or communication errors, which aren't specific to this particular proxy action.

Adding a new subnet

To use a subnet in Foreman, it has to already be configured on your DHCP server. At the moment, Foreman doesn't manage the subnet-level configuration of the DHCP server, so this has to be done either manually or via a Puppet module such as theforeman/dhcp.

You can import some subnet details into Foreman that have already been configured on your DHCP server by going to Infrastructure > Smart proxies and clicking "Import subnets" next to the DHCP proxy server.
