I upgraded Viscosity today, and now I can no longer connect to any of my VPNs; I get the following error:

Cannot allocate TUN/TAP dev dynamically

Any help is appreciated.

Hi kraison,

Would you be able to post the following? If there are any sensitive details please feel free to censor them out before posting. Alternatively you can email us these details if you'd prefer for them to not be in a public forum.

1. A full copy of the OpenVPN log: ... envpn-log/

2. The Raw Configuration Data for your connection. You can view the raw configuration data for your Viscosity connection by opening Viscosity’s Preferences window, holding down the Option/Alt key on your keyboard, right-clicking (or control-clicking on Mac) on your connection, and selecting “View Configuration Data”.
