I formatted and start over a few time, as I keep having mix results.
at this stage unbound don't seems to work at all but when I go back to cloudflare, PiHole is resolving again.
I did follow the instruction on my Raspberry Pi 4 and my conf should pretty much look like this
server:
# If no logfile is specified, syslog is used
# logfile: "/var/log/unbound/unbound.log"
verbosity: 0
interface: 127.0.0.1
port: 5335
do-ip4: yes
do-udp: yes
do-tcp: yes
# May be set to yes if you have IPv6 connectivity
do-ip6: yes
# You want to leave this to no unless you have *native* IPv6. With 6to4 and
# Terredo tunnels your web browser should favor IPv4 for the same reasons
prefer-ip6: yes
# Use this only when you downloaded the list of primary root servers!
root-hints: "/var/lib/unbound/root.hints"
# Trust glue only if it is within the server's authority
harden-glue: yes
# Require DNSSEC data for trust-anchored zones, if such data is absent, the zone becomes BOGUS
harden-dnssec-stripped: yes
# Don't use Capitalization randomization as it known to cause DNSSEC issues sometimes
# see https://discourse.pi-hole.net/t/unbound-stubby-or-dnscrypt-proxy/9378 for further details
use-caps-for-id: no
# Reduce EDNS reassembly buffer size.
# Suggested by the unbound man page to reduce fragmentation reassembly problems
edns-buffer-size: 1472
# Perform prefetching of close to expired message cache entries
# This only applies to domains that have been frequently queried
prefetch: yes
# One thread should be sufficient, can be increased on beefy machines. In reality for most users running on small networks or on a single machine, it should be unnecessary to seek performance enhancement by increasing num-threads above 1.
num-threads: 1
# Ensure kernel buffer is large enough to not lose messages in traffic spikes
so-rcvbuf: 1m
# Ensure privacy of local IP ranges

PS: I tried to set "prefer-ip6" to no to test, but same result.
Firewall everything is running fine with my second PiHole (DoT this time)
all firewall are in the same IP group
