I'm using OpenVPN connection config file from ExpressVPN. It was working fine on Mojave but stopped working on Catalina. Deleting and re-importing connection does not help. Viscosity shows green dot, aka successful connection but no traffic is routed through VPN connection.

Setting Send all IPv4 traffic over VPN connection in Networking tab does not help either. Instead, I'm just not able to open any site in a browser until I disconnect. Log file does not show any meaningful error to me. netstat -rn still shows my default route to my home router. tun adapter is there and seems to get IP address assigned.

Hi Spaider,

Note that you shouldn't be looking for a "default" route with OpenVPN, as it instead uses two routes that override the default route to ensure that all traffic uses the VPN connection. For more information please see: ... connection

Assuming the routing checks out, it could mean a problem with the OpenVPN server or a configuration issue. Please get in touch with your VPN Service Provider and ensure that you've downloaded and imported the latest configurations, as it's possible the ones you're currently using may be out of date.

I also recommend checking your VPN connection's compression settings, as a mismatch between the client and server is the most common reason for VPN connections not working: ... ader-byte/

Thanks for suggestions. Unfortunately, none of the helped :(

What did help, is an installation of latest update. Before that I did not even saw "0/1" route destination after Viscosity connects.
