I recently moved all my lightroom images to a different hard drive. At the same time I created a new catalog and attempted to tidy things up. 

Ever since, Lightroom won't sync some files. The Asset Path/Link is a url (https://lightroom.adobe.com/libraries/ followed by a string of letters and numbers). When I click the path, it leads me to a page with the following error: 

We’re sorry, but Adobe Lightroom is temporarily offline.

We’re aware of this issue and are working to restore access.

Please try again in a few minutes!

See our status page for more info.

It's been like this for a few weeks and I'm now desperate to resolve. 

I've tried unsharing any shared collections and I've rebuilt the sync data. Neither have worked. 

Any help would be much appreciated.
