Hi Community,
I'm still troubleshooting an issue with my FlexVPN server-client setup. Currently, I'm testing on a freshly configured Cisco 4331 running IOS-XE Version 17.09.06.
On the client side, I'm using Cisco AnyConnect Secure Client for Windows (tested with versions 4.8 and 4.9). However, after successfully obtaining the certificate and entering the username and password, the connection fails, and the client session is terminated.
From the router logs, I can see that the session is being closed by the client, but I can't determine the exact reason behind this behavior.
I would really appreciate any insights or guidance on resolving this issue. Debug logs and router configuration are available at the following link: https://drive.google.com/drive/folders/1gYoGXAsul3clMQeGL3nH8bei5JhWqG8P?usp=sharing
Thanks in advance for your help!
