Anycast Down

    I've been using free Nextdns for over a year without any issue. And I decided to upgrade to paid service for what it's worth 2 weeks ago.  

   Ever since then, I've been running into " anycast error" non stop.  Both my router and Android  phone wifi stop working whenerver I apply Nextdns. 

   What a shame for a paid account

    Please provide a traceroute to 45.90.28.0 and 45.90.30.0.

    Note that if you are using Private DNS on android, anycast problems should not affect you.

      NextDNS I've set up my paid  Nextdns account with another  router ( Asus) and ISP at my friend's home, it's working smoothly. But at my home, with different router( TP LINK) and ISP, the issue still remains unsolved. My Android phone is using Nextdns app, not Private DNS. I toggle it on in the app, it's connected for a few seconds and disconnected again. 

         One more thing inconvenient is that I let Nextdns app for Android on at all times on my phone. And when it' s connected with a router configured to use  Nextdns, DNSLEAKTEST show that my phone is using DNS from my ISP. I suppose I can't use my Nextdns Android phone to hook up with a Nextdns router?

         Please note that my friend's router using my Nextdns account is running smoothly. So is my phone with 4G LTE. I think the issue has something to do with my home router? It's a TP LINK mesh and I leave all settings to default.

         Everytime I try to set up my TP LINK mesh with Nextdns, the whole mesh system is down.
