Can not add my own Adguard Home DoT server

[trmdi]

Issue Details

For some reasons I can not add my own Adguard Home DoT server to Adguard for Android.

• DoH still works.
• DoT still works when adding it into Android's Private DNS setting.

Solved by setting the TLS option to have alpnProtocols=dot. (My Adguard runs behind Traefik)

@trmdi — could you paste your complete traefik & adguard configuration for reference? I'm trying to figure this out, but for the life of me cannot figure out how to set alpnProtocols

@ketan

# adguardhome.yml

# DoT
tcp:
  routers:
    dot:
      entryPoints:
        - dot
      rule: HostSNIRegexp(`^([a-z0-9-]+\.)?dns\.example\.com$`)
      service: dot
      tls:
        domains:
          - main: "dns.example.com"
            sans:
              - "*.dns.example.com"
        options: dot

  services:
    dot:
      loadBalancer:
        servers:
          - address: "adguardhome:53"

tls:
  options:
    dot:
      alpnProtocols:
        - dot

btw, can Adguard for Android ignore requesting the dot alpnProtocols like dnslookup/Android system's private dns... do? @Versty
