Linux nextdns version 1.46.0-SNAPSHOT-6e53a79 Not Handling IP Address Change

I am facing an issue where DNS look-ups fail after time with the NextDNS Linux service installed and running. The issue has been reproducible on a Debian Trixie install for days. I am now not reproducing this issue only after adding my changed IP address assigned by my ISP to my.nextdns.io under Linked IP. This IP address will change in the future. When it changes, the Linux tool will break again.

It is clearly stated that when using your own tools, linking IP addresses is not required.  It looks like this feature is broken under Linux.  Windows 11 has no issues with NextDNS tool installed.  All DNS look-ups worked.  Only the Linux tool faced this issue.

    After some time, this is the error I get using nslookup:

    This looks like a bug with the Linux version

      Updating Linked IP address makes no difference.  This is running under VMWare Professional.  Why is the 127.0.0.53#53 server that is local not responding?  This is the cause of the issue.

    A couple of notes here:

    1.  I installed an upgrade to this version, and now version 1.4.6.0 is installed.  The same issue happens with this upgrade.

    2. Adding my changed address under Linked IP makes no difference and does not help.  This issue still happens, and it looks like your bug:

    This has nothing to do with the NextDNS CLI. Linking IP is not required with the CLI if correctly configured.

    I suspect this error is to do with the systemd-resolved service overriding and not allowing the CLI from running.

    Please check that the NextDNS CLI is actually running by entering this command:

    systemctl status nextdns
