Do not download the covers from picard with a development server

I have successfully installed the musicbrainz server in development format. From picard I can perform the search of the audio files and the answer is satisfactory, nevertheless never presents me the cover of the album. If I look for the file directly on the server that I have installed I also get the information from the file but the cover does not appear either.
Do I need to make any special settings for the covers to appear?

I don’t know why you can’t see the covers in your setting, but all the covers are hosted on the external Cover Art Archive, not on one of the MB servers.
