[atlas] Probe not coming online anymore after firmware upgrade

Hi, 

Thanks for having a look :). 

It seems the probe is now working. Still strange is that the v4 network tab is completely empty but the tags say v4 works :D. (Which is true, I checked via tcpdump the probe is talking v4 too).

Best,
Annika
