I'm trying to troubleshoot this DNS I have on a small old Odroid C1 board.
I have set up a static IP, but cannot get DNS to work. The image comes with systemd-resolved by default. I have notes that said to set a static IP, then disable systemd-resolved, and after a reboot the DNS would work, but that didn't work. I've looked into systemd-resolved a little bit, and have configured the DNS servers manually, which is required when using a static address.
My gateway is also my DNS.
Here is what I believe to be relevant output:
/etc/systemd/network/eth0.network:
[Match]
Name=eth0
[Network]
Address=192.168.10.44/24
Gateway=192.168.10.254
DNS=192.168.10.254
DNS=1.1.1.1
Output of resolvectl status
and some pings:

Alternatives to systemd-resolved welcome, just need it to work.
edit:
The solution was to add DNSSEC=no
in /etc/systemd/resolved.conf
. I learned this by running journalctl -u systemd-resolved -f
, which said DNSSEC validation failed for question google.com IN A: failed-auxiliary
.
Literally running into this problem. I have a microsoft account with shared calendar and just can't seem to add it to the outlook app. It keeps trying to go to my domain. There's a button to specify the provider, outlook, but it just won't do it. Can't tell what this closed source garbage is doing wrong, it shows the manual entry fields with my server's info entered wrongfully.
