Back in the day when I switched to a new account and got premium I immediately connected my acc with my FB.
Since then I disconnected and reconnected FB and Spo. several times with no problems at all. It displayed my full name, or my original username.
A few days ago I had to disconnect it again, and when I tried to log in again, typed my acc credentials, pressed ok, the window disappeared, but it didn't connect.
I've tried to do it from my phone, from 2 different PCs - none of them worked.

It's possible that you have opted out of sharing your data with Facebook.
Please check this on your account settings here: https://www.spotify.com/account/privacy
Also, please make sure that you've allowed Spotify to have access to your personal data on Facebook: https://www.facebook.com/settings?tab=applications
I hope these suggestions help you solve this issue!
