/etc/reslov.conf should be symlinked to /etc/systemd/resolve/resolv.conf
lrwxrwxrwx 1 root root 32 Dec 21 2019 resolv.conf -> /run/systemd/resolve/resolv.conf
For some reason this link is not created on some systems. Creating it manually helps.
ln -s /run/systemd/resolve/resolv.conf /etc/
I can check that tonight, but regardless of symlink it didn't update to the proper ip address via anything i had done previously until it got updated manually.
