That documentation is correct. So have you tried troubleshooting each
of these possibilities? Can you ping the IP address or the master
server? Is it running a name server? Is that server answering
authoritatively for the zone? [Repeat these checks for each zone and
master name server.] BTW these are rhetorical questions. Try to
answer them yourself. If you run the master server(s) for these
zone(s), check their logs. Any problems they have should be identified
there.

The error message means something is definitely wrong. The names are
probably not being resolved correctly. Maybe the master (primary)
server isn't authoritative for the zone any more => no zone transfers
=> no authoritative slave (secondary) server => zone expiry and no
zone data at all => the sky falling in. Eventually.

If you'd posted worthwhile information like your slave server's config
file, someone might have been able to check things out for you. But
you didn't so we can't guess what the names of the zones are or the
addresses of the master server. Oh well.
