Homebase 2 stays Offline

I have 2 Homebase2s each with 4 cams - one has been going offline with the red lamp showing. Rebooted via a power cycle - stayed up for a while but now offline and wont come back.
What to do??

I have the same issue. I exchanged the Homebase 2 for a new one at the store but am still unable to get it back online. Has anybody any tips on what to do? Thanks!
