Hi all!

I spent the evening pulling my hair after the migration of my (docker) pihole installs: the entries in the local DNS were migrated, were visible in the webUI under dns.hosts, but they were not working. Any of these would just return NXDOMAIN.

I eventually found out that my hosts were listed in the /etc/hosts file, but v6 uses a /etc/hosts folder, with a custom.list file in it. Deleting the file, putting the values in the hosts section of pihole.toml (or via the webUI), and all is now working as it used to.

I hope this post will save some time to whoever has a similar issue!
