Fiddler Not capturing network request while connected to Cisco AnyConnect

[Alvaro]

Hi, I'm using Cisco AnyConnect secure mobile client ver. 4.8.02042 on macOS Catalina 10.15.7 (19H114) to access the Kibana service for Client project. without AnyConnect we cant access Kibana.
I've to capture some network requests from the Kibana using Fiddler tools for debugging purposes. but when I start AnyConnect Secure Mobile client Fiddler doesn't work or capture any network traffic and if I stop AnyConnect both Fiddler starts capturing network requests.
I have Fiddler Everywhere Version : 1.4.1 Built : Tuesday, December 15, 2020 and i have verify the Mac Proxy Settings when AnyConnect is running and not and everything is the same as  here (https://docs.telerik.com/fiddler-everywhere/knowledge-base/troubleshoot-mac-proxy-settings#verifying-mac-proxy-settings) so i assume that the proper configuration is set.



Thanks in advance.

Hi Alvaro,

Indeed there are some specifics when working with Cisco AnyConnect VPN and proxy configuration. You can check this article how to setup such configuration: https://docs.telerik.com/fiddler-everywhere/knowledge-base/configure-vpn-with-fiddler

Can you give it a try and inform us if it works on your side?

Hello Rosen,

I had fixed the problem, I had to bypass VPN IP and now it's working.

Thanks a lot!
