Fixing Connectivity and Authentication Errors with Cisco AnyConnect VPN
If you are experiencing connectivity and authentication errors with Cisco AnyConnect VPN, there are a few steps you can take to fix the issue.
First, make sure you have the latest version of AnyConnect installed on your device. This will ensure that you have the most up-to-date features and bug fixes.

If none of these steps resolve the issue, it may be helpful to consult the Cisco AnyConnect documentation or reach out to Cisco support for further assistance. They will have the knowledge and expertise to help troubleshoot and resolve any connectivity and authentication issues you may be experiencing.
