Arlo base station and camera offline after updating firmware

[hotaru79]

I had updated the latest firmware today. After update both base station and cameras status went offline.

However the cameras can still record, while it cannot watch the live video.

I already tried to shut down and switch the base station, remap both base station and cameras, but the issue still remains. 
Are there any method to solve the issue? Many thanks.

I've noticed that the last two app updates for Android have resulted in notable delays in loading the devices and library each time I open the app now. The first time I opened app after the second to the last app update, the app would not show any of my devices or library videos. I had to close the app and re-open the app a couple times and then finally rebooted my cell to get everything to show again. I was out of town, so I was pretty stressed that all my Arlo security cameras disappeared.... (note to self: DO NOT update app when out of town).

I did the last app update this weekend. The next morning, I did a power-cycle of router and modem. My Arlo Q and Pro 2's showed as offline, even though the base station showed all green lights. I have never previously had these issues. After I powered cycled the Arlo 2 and base station twice, the base station showed all green lights, but all the devices kept showing offline in the app.

I left it, planning to check this Arlo Community to see if others are having issues. The devices finally showed up the app after at least 10 minutes. I don't think that it's a conicidence that this occurred right after the last update.

@hotaru79  When you describe firmware update, are referring to the base station or Pro 2 camera? Did your app notify you that a firmware update was available?
