I too have a probe that won't come online after being online for months: https://atlas.ripe.net/probes/17879/#!tab-general
I did the reset trick: I've stopped the probe, removed the USB drive, started the probe, waited 5 minutes and inserted the USB stick again. The probe comes up but via the WebGUI it shows offline. The IP is pingable so I am at a loss of what I should now do to get it back into the on-line mode. Any help appreciated. Thanks, Hank
