Im using viscosity from really long time and didn't have such problem

Hi mikel1982,

The "Opening utun (connect(AF_SYS_CONTROL)): Resource busy" messages are normal. They indicate that OpenVPN has detected an adapter is already in use, and trying the next one (e.g. in this case utun0, utun1, utun2 are already in use). macOS uses utun adapters for iCloud and other services, so it's not unusual for several to already be in use.

There haven't been any DNS changes in the version 1.7.8 update, so I recommend running through the troubleshooting steps in the following guide to determine what the issue is:
