Title:
  Vino server stops when connecting to VPN after upgrade to 20.04

Status in vino package in Ubuntu:
  Confirmed

Bug description:
  After I upgraded from 18.04 to 20.04, whenever I am making a
  connection to a VPN server (using Network Manager), vino-server will
  stop when the VPN connection is established.

  This did not happen in 18.04 before the upgrade.

  syslog show the following when I connect to VPN

  10:02:00 systemd: Stopped Vino VNC server.
