I recently tried to reignite a server from another servers ignite recovery archive. At first I did not success. It threw this error in my face
The currently selected configuration does not contain any environments. You may want to select another configuration.
Debugging the error I found that the client did not have an config file in
/var/opt/ignite/clients/<name>/config
And thus lanbooting Ignite-UX threw the error above. I basically just copied over a config file from another server and edited it and all was fine again.
