AnyConnect not working on Ubuntu but it works on MacOS

[mthomaz]

Hi.

I am trying to connect to my Cisco ASA 5516 using Anyconnect, but I'm getting errors.

I've tried this on Ubuntu 19 and Ubuntu 18.

On my MacOS, it works! Using the same credentials and the same router.

Linux client version: 4.7.00136

Does anybody have any idea why this happens? Thanks!

Hm...

In past I use AnyConnect on ubuntu 17.

I will try again and tell you result.

Hi,
Do you have the Linux AnyConnect headend package upload on to the ASA? You will not be able to connect from a Linux OS until you do.

HTH

We've found the issue with Anyconnect on Linux. It's the subnet mask for VPN user which was misconfigured. After I corrected the mask the Anyconnect VPN works.
