I have my System photo library on an external hard disk to save space as my MacBook doesn't have enough. I did this in line with this article:
Move your Photos library to save space on your Mac – Apple Support (UK)
However, the iCloud sync pausing stating "Not Enough Local Storage". There is an absolute ton of space on this external disk so I have no idea why it won't sync.
MacBook Pro 13″, macOS 10.13
Is the system version given below your question still valid? macOS 10.13? Or did you upgrade to a more recent system version?
Have you checked, if Photos is really using the library on your external drive or has switched to a new library on your system volume? Photos may switch to a new library in your Pictures folder, if it encounters a problem with the external drive, for example, if the external drive gets dismounted and the Photos background processes cannot access it, even if you are not working with Photos, when the external drive is not available.
Photos is showing the path to the currently open library in the Photos > Preference (or Settings) > General: Library location. Click the button "Show in Finder" in the "General" tab. is Photos still using the library on the external drive or has it lost the connection?
How much free storage is on the external drive and how large is your iCloud Photos Library? To start syncing with iCloud Photos, after iCloud Photos got disabled and needs to be turned on again, you need at least as much free storage as the size of the library in iCloud, even if all photos from the library are already in iCloud. Photos is estimating the required storage based on the worst case assumption that all items in your library are different from the items in iCloud and need downloading again.

Actually no it is OS 13.6.1. Photos IS using the library on the external disk. Library size is 327.96 GB, free space on that drive is over 1TB.
iCloud syncing is still on, but the message I receive is as stated.
Oh that is odd. I was about to screenshot the message in photos, but it now seems to have started syncing again! I am happy if it has, but no idea why I got the original message. I will update later as to whether it did actually manage to sync the library.
Good luck! Let us know, if he syncing is stalling again.
Yes. It did decide to start working again without me doing anything, and things look pretty good. Fickle!
Photos seems to to sync library on external disk, stating"Not Enough Local Storage".
