I am seeing this in the logs:

2023-02-08 16:06:23: Testing address: [Public IP redacted] Route points into VPN network
2023-02-08 16:06:23: Route: utun10
2023-02-08 16:06:23: Disconnecting connection as it is no longer reachable
2023-02-08 16:06:23: State changed to Disconnecting (Network Change)

2023-02-08 16:06:24: Viscosity OpenVPN Engine Started
2023-02-08 16:06:24: Running on macOS 13.2
2023-02-08 16:06:24: ---------
2023-02-08 16:06:24: State changed to Connecting

I am seeing these disconnects after a seemingly random period of time.

The "Route points into VPN network" is intriguing. Is this a Viscosity or macOS issue? I don't see this on Windows.

I saw this on 1.10.4 and updated to beta version but that didn't change anything.

Hi lkinley,

What is likely occurring is your normal network connection is briefly dropping out. When this occurs, macOS will reassign the default route to the next available interface (which is typically going to be the VPN network interface, which obviously won't work as it would result in VPN traffic being routed into itself). If you're using a Wi-Fi network, it's likely dropping out briefly. Try moving closer to the Wi-Fi access point, or look for things that could cause it to drop briefly (like a microwave). If you're using a wired network, it could point to a problem with the cable or the switch/router it's connected to. Cheap USB ethernet adapters can also sometimes have issues.
