I noticed a consistent and reproducible issue on my Mac running Cura 4.4.1
Whenever I am connected to an OpenVPN connection (how I sometimes connect to OctoPi/OctoPrint) Cura will not start the slicing process.

Now that I've determined that it is an OpenVPN connection causing the issue, I've been able to reliably work around it by disconnecting my VPN before slicing. I was just curious if there was something I could do to get them to play nice together.
