iMessage is not working on M2 MacBook Pro.

OS 15.5.

iMessage is turned on in iCloud.

Won't sync messages.

Won't sync photos.

Didn't receive the notification to sign in to this support community on this device, but I did get it on the iphone.

I can manually sync and it will pull everything in. On either device.

This just started a few hours ago.

I'm stumped.

Please help.
