2c Camera Stopped Connecting to Homebase

Hi,
I have a eufy 2c camera which for some reason has stopped connecting to the homebase. It has been working fine since installation which was only 6 weeks ago!

As per your help page I have removed the device and tryed to “add device” like you would if it was a new one but when it says hold the sync button for 2 secs until it beeps it never beeps. The homebase then fails to discover it

The battery of the camera was at 90% yesterday before it stopped working!

Any help would be great,

Will
