I have this problem too,...  and have had it prior to 17.04. Tried 
various configurations of systemd-resolved but the only way around the 
problem seems to be a cron job:


*/10 * * * *  /usr/sbin/service systemd-resolved restart


The reason it has to be a cron job is that if you run the command one 
time,  problems again show up within about 10 minutes or less/more.
