Base station requires updated but battery too low

[denuitct]

Base station has the message:

"A firmware update is required for this camera but its battery levels are too low to proceed".

However, it's a base station, it does not have any battery. 

Clicking "Update" won't get the devices updated. This has been stuck for many days.

Have you tried turning the base off, wait for 10 seconds or so and then turn it back on? No guarantees...

These are the things that I've tried:

• Ensured the other camera batteries are full charged.
• Restart the base station a few times.
• Unplug the power and turn it back on a few times.

The problem still persists.

I gave up.

Today I checked again, it seems like the problem itself is gone, not sure why.
