Jfyi, via IPv6 I never get back anything, via v4 I get the document
and it seems fine at this time (i.e., well-formed and schema valid).

Here's how you can check that for yourself:

Seems it was not fine just before, as clearly the software says
there's an invalid element in there.

wasn't able to read the backup file either.
Maybe check file and directory permissions.
