Hi Phil,

From my limited knowledge of systemd-resolved I don't believe it's strictly necessary, so yes disabling it is worth a try.  You might need to also check the contents of the /etc/resolved.conf file to check that it's pointing to a known-good DNS server.  Or alternatively you could simply restart the machine afterwards and see if it's now reaching the internet.
