"Private DNS" on Android and pfSense DNS setup conflict?

Hello,

I use NextDNS's DNS, both on the "Private DNS" setting on my Android phone, and on the DNS Resolver custom option of my pfSense router.

It worked for months together (I use my NextDNS phone config , both on 4G and when I'm connected to my router.).

But since a few hours today, without any configuration modifications,  my phone tell me no internet connection when I'm connected to the router.

It work great on another wifi (without NextDNS setting), or on my wifi (with nextDNS Settings) but only if I disabled the "Private DNS" setting.

I don't know why...

Is there a conflict when we use both NextDNS setting on router AND on phone together?

Thank you,

      Olivier Poitrey thank you for replying :)

      On 4g with private DNS :

      {
      "status": "ok",
      "protocol": "DOT",
      "configuration": "fpb9d8a0772d538e04",
      "client": "redacted",
      "destIP": "45.90.28.0",
      "server": "netbarista-par-1",
      "clientName": "unknown-dot"
      }
      On Wifi (so with router DNS resolver with NextDNS) AND with no "private DNS" android setting :
      {
      "status": "ok",
      "protocol": "DOT",
      "configuration": "fp63ff6da8091c759a",
      "client": "redacted",
      "destIP": "45.90.28.0",
      "server": "netbarista-par-1",
      "clientName": "unknown-dot"
      }

      And I cannot test on wifi AND private DNS, because these is no DNS resolving (that's the problem I describe here), so no internet :D

  • I don't know if it's important but I use mutiwan on router (ADSL, 4G and VPN).  And pfSense ask for DNS on all interfaces. (But it was working like this for months..)

      Ok, good new. Ask me if you need to debug some things.

      Is there a solution to enable DNSSEC both on router, on phone, AND on phone when connected to the router wifi?

      It's look like there is no DNSSEC on router anymore (but it is normal as I disabled it on DNS resolver :)

      Like
    • fwehrle you can help by providing the output of the dig command that was failing before.

      Regarding DNSSEC, we are validating DNSSEC for you. As we need to modify responses for filtering, it is discouraged to validate DNSSEC on the client as validation will break when a domain is blocked or rewritten (rewrite feature, safe search feature etc.).

  • I've noticed android devices have not had connectivity for approximately 36 hours. I use a similar setup as Fwehrle. Turning off DNSSEC in PfSense does not eliminate the "Private server cannot be accessed" message on android users devices. Any other thoughts for how to solve this?

    Thanks

      Hi Olivier Poitrey , I've disabled DNSSEC but android devices are still showing the same error. I'm testing with a Pixel 3, I've tried restarting the device and turning Private DNS off and back on. As soon as I hit Save it says it couldn't connect to the private DNS server.

      Thanks

  • Olivier Poitrey following up on this. I last posted on Dec 23rd. A few days later the issue went away with no configuration changes on my end. I assumed something was adjusted in NextDNS. As of approximately 12 hours ago the "Private DNS cannot be accessed" message is back for android devices.

    Thanks

      Olivier Poitrey Sorry, to clarify the CNAME Flattening setting is and always was disabled for my account. The problem is still occurring.

    • eBKv6q do you have dnssec validation setup on your router? Does it fix if you disable (I know you tried in the past, but this is a different issue).

      Olivier Poitrey I still have dnssec disabled on the router. Its been off since my initial post on Dec 23rd.

    • eBKv6q If your using Pfsense then it's probably Pfsense and not NextDNS. Your android devices are not being allowed to reach the surface. It stays within the local network. Adjustments would need to be made to allow your devices to get through Pfsense or it will be automatically blocked.

  • Any updates on this issue? I've experienced the same "Private server cannot be accessed" on android devices for the last 2 weeks.

  • I have been experiencing the same "Private server cannot be accessed" error, with no changes having been made on my network.  I am on Verizon FiOS and using the G1100 router. 

    I am not aware of any way to enable dnssec on the router.  Also, I have CNAME flattening disabled.

    Any other suggestions on resolving this?

    • wTm5PK Can you try:

      1. Using "dns.nextdns.io"

      2. Using "anycast.dns.nextdns.io"

      And for which one(s) you're getting the issue?

      Romain Cointepas can you clarify what we should be trying? Should we visit the two URLs in our browser, or try swapping Android Private DNS to the format device-ID.anycast.dns.nextdns.io rather than the normal device-ID.dns.nextdns.io ?

      Thanks

      Romain Cointepas anycast.dns.nextdns.io fails to connect consistently, but I have never used that prior to the test you suggested.

      I was originally using dns.nextdns.io when receiving the error. It appears to be working now, but I was sometimes able to get it to work by manually switching from dns.nextdns.io to hardcoding dns2.nextdns.io.

  • Thank you.

    I don't know if it apply, since I don't know how to check the CA on pfSense.

    I ask for it on the other post. Wait and see..
