Photos is Locked

I have been trying to upload photos on my MBP to iCloud.

Has always taken a while but eventually they come through.

I have tried many times in the last few days with the sign 'Photos is Locked',

What does this actually mean?

I have enough space in iCloud and Photos.

Never heard of photos being locked, but perhaps this might shed some light on the issue -- locked photos - how find, unlock?
