I've not ripped any CDs for a while but just tried and hit the same issue. My X10 was using freedb.org to get CD information. This was taken over by Magix in 2006 but they pulled the plug on freedb and its services in March 2020. Musicbrainz.org is an alternative free source but I'm not sure if this is any way compatible.
It is possible to install the freedb database on the X10 and there is a clear explanation here:

The 1.1GB zip file indicated is dated 08/04/20 but I don't know how up-to-date the contents are nor if it will be updated in the future.
