Proxyman does not work with VPN apps
Troubleshooting why Proxyman doesn't work with some VPN app, and how to fix it if possible
In general, VPN apps might conflict with all Web Debugging Proxy apps, includes Proxyman, Charles Proxy, Fiddler, and Wireshark.
This troubleshooting would describe what VPN services that work and do not work with Proxyman and how to fix it.
Problems
Proxyman could not capture any HTTP/HTTPS Traffic when you're using VPN apps.
How to fix it in general
Basically, the VPN app would force all traffic that goes through the VPN Server instead of the Proxyman Local Server (127.0.0.1:9090). Therefore, Proxyman could not capture the traffic.
In order to fix it
Open your VPN's Preference and try to find a text field that you can override the HTTP/HTTPS Proxy.
If it's available, let override to the address: 127.0.0.1 at Port 9090
If it's not available, please google "<Your VPN Name> config HTTP Proxy" and see how to do it.
Then, Proxyman can capture and works with your VPN app.
List of VPNs that work with Proxyman/CharlesProxy/Fiddler

4. Pulse Secure and Global Protect VPN
Solution 1:
First, you need to install OpenConnect.
You need to obtain the installation path for openconnect
After that, don't forget to edit /etc/sudoers
Add this line and replace <openconnect-binary-path> with your binary path.
Now, you can connect to your secured proxy using Juniper SSL / Pulse Connect Secure protocol.
Once connected, launch Proxyman and it will work like a charm.

1. Sophos
Sophos doesn't work with all Web Debugging Proxy apps. It's a known issue from Sophos and there is no solution to fix it.
Please try to ask your Security Team to try to set the HTTP/HTTPS Proxy from Sophos.
Update: Sophos 10.0.4 (A/V Endpoint Protection) might work with Proxyman with a new network proxy extension, but it has a known issue that causes massive CPU Spikes. It's going to fix in the upcoming EAP.
