unbound not working

[Veraellyunjie]

Trying to set up unbound on OpenBSD with help of this tutorial:
https://www.jwillikers.com/dns-over-tls-with-unbound

Go to https://www.rethinkdns.com/configure
Toggle DoH/DoT to see Using DNS-over-TLS pop-up
See max.rethinkdns.com

It's insufficient for unbound - you need an IP - see tutorial above.

Use howto from m0zgen/openbld.net#2

> nslookup -port=53 max.rethinkdns.com 1.1.1.1
Server:         1.1.1.1
Address:        1.1.1.1#53

Non-authoritative answer:
Name:   max.rethinkdns.com
Address: 137.66.7.89

We got 137.66.7.89 IP; check it works:

> telnet 137.66.7.89 853
Trying 137.66.7.89...
Connected to 137.66.7.89.
Escape character is '^]'.
Connection closed by foreign host.

seems to work.
Put forward-addr: 137.66.7.89@853#max.rethinkdns.com into unbound.conf
Run rcctl reload unbound
Try pinging/opening some website. ping: no address associated with name, browser: ERR_NAME_NOT_RESOLVED
