That's because ".local" is an unfortunate choice for TLD, as it is used in
networks without central server.
Many systems will look in mDNS over DNS for .local hosts, and complain if
nothing found.

Use a different TLD than .local.

Also, you could remove that "legal" appendix from public list postings, it only
irritates the readers, adding nothing of value to the message itself.
