NextDNS stopped working on all my devices
Since last night, NextDNS has completely stopped working on all my devices, no matter the method I use to access it.
PCs usually use Yoga, which gives the message "drop request because IP address of the server is not yet known". Using the NextDNS app (beta) doesn't work.
My Android phones are unable to connect.
My base network defaults to using just IP addresses given over DHCP, these don't work.
My internet is fine, if I switch Yoga to use Cloudflare, all resolution happens and is fast.
What are my next steps to diagnose? Are there any known issues? This isn't the first time this has happened, it just usually clears faster.
Feel free to delete, solved.
Seems my ISP modem (Virgin Media) had failed in some weird way that allowed some DNS through and not others. This was stopping Yoga and NextDNS apps from getting their initial lookups which they hand over to the system resolver. I had restarted my entire UniFi system up to the USG and nothing had worked. Power cycling the modem seems to have cleared it all. Guessing the Android phones were failing to connect to nextdns even on 5G due to too many attempts whilst on WiFi
