impossible connection of private DNS on Google pixel 6

hello, since this morning, it is impossible for me to connect to the nextdns service on my pixel 6 updated with the may patch.  Is there a breakdown?

      NextDNS I seem to have the problem back again as well. Everything has been working smoothly since the fix was deployed up until today.

    • Sea Wolf it is likely a different problem as nothing has been rolled back. What is your ISP?

      NextDNS I'm on Telstra Australia. The issue does seem to be intermittent and specific to DoT, if I use DoH the problem isn't there.

  • Hello,

     

    01) Could you try to be more specific about your issue

    02) Have you tried doing things like https://ping.nextdns.io/ and https://test.nextdns.io (Make sure to turn off in-built DNS-over-HTTPS on browser if it supports that, e.g Vanadium, Bromite, Kiwi, Iceraven, Fennec and Mull for instance)

    03) Are you using the native Google Android or an alternative such as GrapheneOS, CalyxOS or DivestOS?

    (Not a support staff but you aren't really giving any details to go on for them or the community, please provide as much details as possible so the staff and community can try to help)

    Note: Fellow Pixel 6 user here without any issues on GrapheneOS with Private DNS.

      Off-Topic, but beware that your device becomes EOL within 1 year and 4 months.

  • I've been experiencing a lot of "Can't connect to private DNS" issues on my Samsung Galaxy S21 with android 12 on it. I tried the pin site, and got a ton of errors. Any suggestions? Can I share my logs with the support staff in some way?

  • Please try with IPv6 disabled on the device to see if it helps.

    • NextDNS do we do that on the NextDNS control settings on the website? Or on our phones somewhere? Not seeing anything mentioning that on the site. 

      I see IPv6 mentioned under Endpoints, but I'm not using that. I'm using the Private DNS. 

      To be clear, this is happening on mobile data, NOT WiFi.

    • NextDNS update - Found it deep within Settings on my phone -> Connections -> mobile networks -> Access Point Names -> edit APN. Unfortunately the entire APN screen/list of options is disabled. 🤦

      Reony Tonneyck your ISP doesn’t provide IPv6. You can’t change anything here but switching to another ISP

      Plus, I wanted to use the NextDNS app, but it creates a VPN connection to provide DNS configuration. Android does not support using two VPNs at the same time, and I already use another VPN connection to access my home network.

      According to previous posts in this thread, it looks like IP6 support by the mobile carrier is problematic. Could it be circumvented by providing alternative DoT adresses that would resolve to IP4-only or IP6-only resolvers? e.g. configid.dns4.nextdns.io and configid.dns6.nextdns.io

      Thanks!

      On second thought, is it sure it is about IPv6? when I use different IPv6 connectivity tests using default DNS, everything seems reachable, even IPv6 DNS resolvers. But switching to nextdns make all tests fail. It's a bit strange, as if NextDNS was specifically filtered. Is there a way to check that?

  • Same issue with Pixel 6 recently updated to Android 13 (the problem apparently predates this)

    Consistently says "Private DNS server cannot be accessed."  either with or without the App.

    Works fine with WiFI, though it kind of struggled before IPV6 was enable on my network.

  • Same here, Pixel 6 pro it used to work then suddenly with Nextdns app works but private DNS no, while on wifi, via mobile network works fine.

    If I try one.one.one.one it works fine.

    I don't think this depends on the wifi network operator, because I have configured my home router to use nextdns and all other devices work fine.

    Like
  • It's mostly Ports being blocked by the network provider. I was using Vodafone where I live and they were blocking the DoT port so I couldn't use Private DNS. So if it's working on one network like home WiFi and not on Mobile or vice versa it's likely the network blocking it.

    Pretty sure I heard that T-Mobile also has issues when you have some Parental Control / Safe DNS options provided by them.

    • My wife's phone works fine with the same connection, so i doubt that it depends on the network provider.

  • Hi there

    Only me and my family's two Pixel6a's can't reach the internet from the home network, but I think this is probably the case in our case. (IPv6 and v4 are coming to the router, wifi is a bridge)

    I'll review the network to try and fix the problem.

  • I'm now experiencing this issue as well. Been using NextDNS through private DNS setting on a Galaxy S22 Ultra with Telstra in Australia. Suddenly it stopped working while on mobile date, but works fine when I'm connected to WiFi. If I use the NextDNS app I'm able to connect and if I change the private DNS setting to a different provider (ControlD, Cloudflare etc.) then it works fine, so whatever the issue is it's specific to NextDNS.

    Telstra has been gradually moving to an all IPv6 network, so it's possible that I've been cutover and that's now part of the problem.

      Gui Gast The problem is only going to keep spreading as more mobile providers move to single stack IPv6. Whatever the issue is it seems to be unique to NextDNS, I'm having trouble using ControlD instead now.
