Issues connecting to Photos Library that is in a server.

Hi guys, good night to you.

I'm having some issues with my new two acquisitions that are a 2013 MacBook Pro 15-inch Retina and a WD MyCloud Mirror 6TB. My Photos Library was in my old Mac and I uploaded it to the server, but now it's unaccessible. I already made some search and I found this If Photos can't create, upgrade, or open your library because of file system issues - Apple Support, but I still don't know how to solve my problem. I would really appreciate any help with this.
