Error 'The remote host cannot be found' is issued when the user is forwarded to a child server behind a NAT

In a multi-server setup, when the Cloud Server is configured to forward the user's connection to a specific child server and such host is not reachable directly by the NoMachine client (e.g. because it's behind a NAT), users get an error similar to:

The remote host 'testdrive.nomachine.com' cannot be found

 

As a temporary workaround, force 'tunnel' as forward method for the child server, e.g.:

nxserver --serveredit testdrive.nomachine:4000 --forward-nx-methods tunnel
nxserver --serveredit testdrive.nomachine:4000 --forward-ssh-methods tunnel

The same when adding a new child server:

nxserver --serveradd testdrive2.nomachine:4000 --forward-nx-methods tunnel
nxserver --serveradd testdrive2.nomachine:4000 --forward-ssh-methods tunnel
