Error:Metadata Lookup (invalid mbid.) / Error: Metadata lookup (undefined)

FYI: It was because temporal MB server inaccesibility, tracking as https://www.ventismedia.com/mantis/view.php?id=19556 to improve the messaging.

Thanks for looking into this Ludek,

I am not certain I understand why MMW4 does not show a "temporal MB Server inaccessibility" whereas MMW5 does. Remember, I submitted auto-tag using both MMW4 and MMW5 at the same time / same network / same country ... several times.

Is this "error" not detected as well / or suppressed in MMW4 for example?

Is the "dialogue" between MMW4 and the server different to that from MMW5?

From a user view point the error seems to be specific to certain files and I was sort of expecting to get the same issue in both MMW4 and MMW5.

Hope this is helpful.

MM4 does not use our MusicBrainz server for auto-tag. It used to have utilized Amazon in the past, but AFAIK the only way to auto-tag in MM4 is now using third party addon (from Discog)
