nprobe should not give up trying to connect to the license server

[marcoeg]

nprobe stops trying to connect to the license server instead of keep trying. See log below where it stops trying after only two minutes and four attempts.

A continuous retry is recommended, perhaps with a backoff algorithm. After a power down for instance, it may take a long time for the network to be available at the restart.
