Lately, cover art fetching from fanart.tv stopped working. The site appears to be functional but I guess they changed some API functions. I inspected it using Fiddler and here's the connection log:
504 HTTP webservice.fanart.tv
/v3/music/albums/27202a2d-3a0e-3661-aed0-74a63309db1d?api_key=a1defe334973c1e0678a1 512
no-cache, must-revalidate
Can I somehow fix this by modifying something within MusicBee?
