AnyConnect – The VPN Connection Failed (Domain Name Resolution)

Advertisement

KB ID 0001236 Dtd 15/09/16

Problem

This is a pretty generic error to be honest.

VPN unsuccessful doman name resolution

AnyConnect Secure Mobility Client

VPN

The VPN connection failed due to unsuccessful domain name resolution.

 

Solution

Firstly, (and obviously) the name you are typing in the AnyConnect window can be resolved can’t it? If not then you might want to consider some employment that does not involve computers.

Secondly (this is what usually trips me up) did you copy and paste the name? If so is there a space on the end?

AnyConnect DNS Name

This name may also be incorrect in the profile.xml that’s associated with this VPN, to check, the location of that file is covered in this article.

Also check that the VPN device, does not need to be connected to on a different port, as per this article.
