PAW DNS lookup failure for: wa-proxy

Hi I installed paw workspace 2.36 on a windows 2016 VMWare machine
The planning analytics version is 2.06
Docker version : 17.06.2 --ee–16
The admin tool starts up. All the containers are running
When I start the paw tool (IE) --> I get the following message
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /.

Reason: DNS lookup failure for: wa-proxy

Any idea how this can be solved
