AI Overview
To stop Chromium from using DNS over HTTPS (DoH), navigate to your
browser settings, go to "Privacy and security" then "Security", and
under the "Advanced" section, toggle off the "Use secure DNS" option;
this effectively disables DoH in Chromium.
Or follow any of the human-written links that are provided as well.
it still disabled after turning that off, Greg. Only works if I use the
ipv4 address of that 3d printer. Noticeably a hell of a lot faster than
firefox-esr which is why I liked it in the first place. Is there
something else I should turn on?
This is a known problem of the chromium engine.
It's called 'Async DNS resolver'.
<https://bugdrivendevelopment.net/browser-ignore-internal-dns/>
gives some hints that you may try, but according to
<https://stackoverflow.com/questions/78393737/chrome-ignores-local-dns-despite-flag-settings>
they don't work (anymore?).
What I've read (in an artice in a German magazine that's behind
a paywall (<https://www.heise.de/select/ct/2024/9/2406014455006618241>)
the only thing that really works is if you setup your own DoH server
and tell Chromium to use it:
In chrome://settings/security:
- enable "Use secure DNS"
- "Select DNS provider": "Add custom DNS service provider"
But I haven't tried it myself.
