Hi,
I am able to run a sample AppProxyProvder::Transparent Proxy sample project on my MacOS (10.15.4). Below are the logs from instance when I open a connection with remote server 192.168.1.10 at port 8080:

Though there was one issue which I couldn’t debug, where I need to install the system extension twice to successfully connect the VPN. Otherwise VPN connect is failing with error [Domain=NEAgentErrorDomain Code=2 "(null)"]

What could be thet issue that VPN connect is failing after 1st system extension install?
