DNS lookup failure for: wa-proxy

Product:
Planning Analytics Workspace 35
Linux Red Hat

Problem:
You have no access to the paw, and a restart of the docker containers with command  ./paw.sh stop  and  ./paw.sh  did not help.

If you click “validate” inside the Workspace administration page, you get Error getaddrinfo ENOTFOUND on all the server links.

Error Message:
Proxy Error
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

Workaround:
Restart the linux box.
Login to the linux server with PUTTY.
Change to root user with command:
sudo su – root
Restart the linux server with command:
init 6

Try again after a few minutes.
