DoH with Adguard Home container behind Caddy reverse proxy

Hi,

I know that this topic is discussed here pretty frequently, however, I
wasn't able to solve my problem after reading previous posts. I run
the Caddy container on my VPS, and both Caddy and Adguard Home are in
the same docker bridge network.

Caddyfile contains these lines:

    http://adguard.example.org:80 {
      reverse_proxy http://adguard:80 {
        header_up X-Real-IP {remote_host}
      }
    }

    adguard.example.org:443 {
      reverse_proxy adguard:443 {
        header_up X-Real-IP {remote_host}
      }
    }

During the Adguard Home installation wizard, I selected port 443 for
the dashboard, since port 80 did not work for me for some reason.
Everything worked fine before I started configuring the encryption in
the GUI:

[Error: control\/tls\/validate | validating tcp ports: duplicated
values: \[443\] | 400](https://preview.redd.it/a0caztqt7rzb1.png?width

These settings lead to an error message:

>Error: control/tls/validate | validating tcp ports: duplicated
values: \[443\] | 400

I checked the config file AdGuardHome.yaml and found the following:

    http:
      pprof:
        port: 6060
        enabled: false
      address: 172.20.0.3:443



    tls:
      enabled: false
      server_name: adguard.example.org
      force_https: true
      port_https: 443
      port_dns_over_tls: 0
      port_dns_over_quic: 0
      port_dnscrypt: 0
      dnscrypt_config_file: ""
      ...

So, I really have two conflicting mentions of port 443. However, I
cannot do anything with the *http* section: changing the port from 443
to 80 does not work. I tried to change the port from 443 to 3000 in
the GUI (see the screenshot above), and it even works but I wouldn't
like to bypass my reverse proxy and open the dashboard with this
alternative port instead of the more common
*https://adguard.example.org*.

Can you advise anything?

You write about use VPS. You use cloudflare? He have support tunnel
(reverse proxy)

Cloudflare tunnel can proxy external traffic on your local machine
(any port)

Hi, no, I do not use it. So far,  Caddy has met my needs.
