      @pietsnot56 not sure what you could be doing.. Click Click and using dot to 1.1.1.1

      test.jpg

      Even did a sniff on wan to validate talking to them over 853

      And can see in the resolver status, its only talking to them.

      edit: now back to normal resolving - not a fan of dot.

        I have similar results in status/ dns resolver with my settings.

        Those are absolutly identical to your setup.

        idem for "1.1.1.1/help"

        Debug Information
        Connected to 1.1.1.1 Yes
        Using DNS over HTTPS (DoH) No
        Using DNS over TLS (DoT) Yes
        Using DNS over WARP No
        AS Name Cloudflare
        AS Number 13335
        Cloudflare Data Center BRU
        Connectivity to Resolver IP Addresses
        1.1.1.1 Yes
        1.0.0.1 Yes
        2606:4700:4700::1111 No
        2606:4700:4700::1001 No
        1.1.1.1 FAQ Terms Privacy Policy Purge Cache

        Could there be a wrong firewall rule that makes the custom settings necessary?

          Sure wouldn't think so.. Any firewall rules would apply if using custom or not.. Are you not hitting save somewhere?

          You need to set the dns in general, before you set the unbound to forward and dot mode.

            The dns settings in the “general setup” are ok.
            I have tested several times with and without the custom settings. Only “with” allows me to browsing on the internet.
            As far i can see all the rest seems working correcty : lookup, 1.1.1.1/ help, ect.
            I don’t understand that your settings doesn’t working on my firewall. ???

              @pietsnot56 the gui settings do what your doing in custom..

              So I again set this back with simple click.. And then look in my unbound.conf

              cat /var/unbound/unbound.conf

              And you will see this

              # Forwarding
forward-zone:
        name: "."
        forward-tls-upstream: yes
        forward-addr: 1.1.1.1@853#cloudflare-dns.com
        forward-addr: 1.0.0.1@853#cloudflare-dns.com

              then I undo the check marks and it is gone.

              while what your doing is doing the same thing really - it makes no sense that you would have to use the custom options to get those settings into your unbound.conf file

              You really should be setting the name, or your not actually going to verify your talking to clouldflare.. Are you not doing that with custom?

                Hi,

                Version 2.6.0-RELEASE (amd64)
                built on Mon Jan 31 19:57:53 UTC 2022
                FreeBSD 12.3-STABLE

                The system is on the latest version.
                Version information updated at Sat Jan 21 14:35:40 -01 2023

                DNS Servers
                1.1.1.1
                cloudfare-dns.com
                1.0.0.1
                cloudfare-dns.com
                .......
                DNS Resolution Behavior

                Use local DNS (127.0.0.1), ignore remote DNS Servers

                A) Config file

                1 ) this is what i have with the "custom settings on" in the config file.

                Domain overrides

                include: /var/unbound/domainoverrides.conf

                Forwarding

                forward-zone:
                name: "."
                forward-tls-upstream: yes
                forward-addr: 1.1.1.1@853#cloudfare-dns.com
                forward-addr: 1.0.0.1@853#cloudfare-dns.com

                Unbound custom options

                server:
                private-domain:"plex.direct"
                forward-zone:
                name:"."
                forward-ssl-upstream: yes
                forward-addr: 1.1.1.1@853
                forward-addr: 1.0.0.1@853
                server:include: /var/unbound/pfb_dnsbl.*conf

                1. by erasing the custom settings:

                Domain overrides

                include: /var/unbound/domainoverrides.conf

                Forwarding

                forward-zone:
                name: "."
                forward-tls-upstream: yes
                forward-addr: 1.1.1.1@853#cloudfare-dns.com
                forward-addr: 1.0.0.1@853#cloudfare-dns.com

                Unbound custom options

                server:
                private-domain:"plex.direct"
                server:include: /var/unbound/pfb_dnsbl.*conf

                3 ) by unchecking "use SSL/TLS for outgoing..."

                Domain overrides

                include: /var/unbound/domainoverrides.conf

                Forwarding

                forward-zone:
                name: "."
                forward-addr: 1.1.1.1
                forward-addr: 1.0.0.1

                B) error file with Use SSL/TLS for outgoing DNS Queries to Forwarding Servers checked on and without custm settings.
                IP6 ????

                Can this help you to expain?

                  Where are you putting in IPv6? I do see it in your output you posted.

                  And looks like you have stuff in there twice

                  forward-zone:
name: "."
forward-tls-upstream: yes

Unbound custom options

server:
private-domain:"plex.direct"
server:include: /var/unbound/pfb_dnsbl.*conf

3 ) by unchecking "use SSL/TLS for outgoing..."
Domain overrides

include: /var/unbound/domainoverrides.conf
Forwarding

forward-zone:
name: "."
forward-addr: 1.1.1.1
forward-addr: 1.0.0.1

                  One would be with tls the other would not be.. You got something messed up that is for sure..

                  Your info might be easier to read if you used the code option for text so it in specific box vs just long running text..

```sometimes 
forward-addr: 1.1.1.1@853#cloudfare-dns.com
with #cloudfare-dns.com at the end

and in the custom settings :
forward-addr: 1.1.1.1@853``
without #cloudfare-dns.com.

can this help us to find the reason?

                          Thanks everybody,
                          I founded my error : a typo in the Dnsname!
                          This case can be closed.
