High Sierra Won't Connect to Magic Keyboard

[BigxMac]

I installed high sierra and everything seemed to work fine. After a restart now my magic keyboard won't connect. It won't appear in the Bluetooth menu and when I try to add it under Preferences > Keyboard > Set Up Bluetooth Keyboard it appears, but says "Couldn't connect to the device". On the keyboard itself the green light just keeps blinking as if it were ready to pair. Any help is appreciated

Pair the Magic Keyboard? I'm using the Magic Keyboard with zero problems in High Sierra.

Did you try powering down the keyboard and powering it back up? I've had a few issues over the years and had to do that.

Sometimes it helps to remove the keyboard and add it again as a bluetooth item if that is an option.

If you use the latest rechargeable Magic Keyboard, try pairing it using lightning cable.
