CasaOS(Zimaboard): Pi-Hole local hostname problem in web browser

[Bucking_Horn]

@cos

When typing in "nslookup pi.hole", I get

Server: server.home.lan
Address: 192.168.178.77

Name: pi.hole
Address: 0.0.0.0

You want to set FTLCONF_LOCAL_IPV4 (recommended environment variable) for your Pi-hole container to the IP of the machine hosting Docker. (It's not clear from your output whether that's 192.168.178.77 or 192.168.178.222, or maybe some other IP.)
