Error handling is incomplete when connecting to a NNTPGrab server using a different API version
|Assigned to:||Alguno||% Done:||
When a frontend tries to connect to a NNTPGrab Server which uses a different API version as the frontend then a dialog is shown.
This dialog contains the text 'Unable to connect to NNTPGrab server:' without the exact reason.
A more verbose reason needs to be shown for this situation
