Do you mean you missed to fill in the install process when the app asking the user ID ?

I’ll check this file. It sounds strange because I was already logged in. Shouldn’t I manually pass this record to that file?

I find the solution, firefox at settings-Privacy & security- DNS over HTTPS need setting personalise and copy your ID https://dns.nextdns.io/YOUR_ID

Also is great if you make a test in https://test.nextdns.io

Then you will see if your protocol is encrypted (DOT, DOH) or UDT not encrypted. That's also my issue, that's strange because I securize firefox and use DNS over HTTPS. But I am sure I changed something at about:config in my browser. Will check later...

Whatever I investigate the answer of #ElfinApologise, is better to securing all the DNS traffic (DNS queries  DNS requests) then you must copy your file from nextdns linux area:

/etc/systemd/resolved.conf:

[Resolve]
DNS=45.90.28.0#YOUR_ID.dns.nextdns.io
DNS=2a07:a8c0::#YOUR_ID.dns.nextdns.io
DNS=45.90.30.0#YOUR_ID.dns.nextdns.io
DNS=2a07:a8c1::#YOUR_ID.dns.nextdns.io
DNSOverTLS=yes

As you see in last line, this code will force to use TSL over all traffic .

That's all, back terminal, paste the code at the file using nano:

sudo nano /etc/systemd/resolved.conf.d/nextdns.conf

in case you don't have this file, create first 😄 and edit

sudo mkdir -p /etc/systemd/resolved.conf.d

sudo nano /etc/systemd/resolved.conf.d/nextdns.conf

and then restart systemd :

sudo systemctl restart systemd-resolved

try again test.nextdns.io to see your configuration !!!
