Topic: Ripper X & Asunder CD Ripper

This happened because of FreeDB CDDB downing:

freedb.org and its services was scheduled to be shut down on March 31 of 2020. As of May 28, 2020 the site was still operational.
On the 13th of June 2020 it was observed that the URL used for lookups, freedb.freedb.org, no longer resolved to a host name and as a result the service no longer appears to operate.

You have to try switching Asunder to GNUDB:

1. Open Asunder
2. Select Preferences
3. Navigate to Advanced tab
4. In CDDB area change server from freedb.freedb.org to gnudb.gnudb.org
5. Retry CDDB Lookup with Audio CD inserted

For RipperX do the following to switch it to other CDDB site:

1. Open RipperX
2. Click Config
3. Navigate to CDDB tab
4. In CDDB Configuration are change URL from freedb.freedb.org/~cddb/cddb.cgi to freedb.dbpoweramp.com/~cddb/cddb.cgi
5. Retry CDDB retrieval with Audio CD inserted.

I have checked both above servers with CD disc dated 1994.

Notes: there is 3rd alternative with port 80 - http://us.cddb.com/~cddb/cddb.cgi.

For asunder look in your home directory for a hidden .config folder. Open that and edit the file asunder with a text editor to replace "cddb" with "gnudb.gnudb.org".
