Just switched from Viasat to a Hughes business account. This problem did not exist with Viasat and does not exist when connected to the internet via my hotspot. When I connect to VPN while connected to Hughes, I have no DNS resolution into my AD domain. RDP fails with cannot find the computer, ping fails with cannot find host. Download the Cisco AnyConnect VPN for Windows installer. Double-click the InstallAnyConnect.exe file. When a message saying the Cisco AnyConnect client has been installed, click OK. Connect to the Stanford VPN. Launch the Cisco AnyConnect Secure Mobility Client client. The VPN connection failed due to unsuccessful domain name resolution when I entered the domain name of router's interface g0/1 from nslookup (server 8.8.8.8). Updated2: I could do forward nslookup but reverse lookup (domain name - IP) returns failed. Is it a problem? Update3: In router's config: ip name-server 8.8.8.8.

[solved] how to resolve the Cisco Anyconnect error message “VPN connection failed due to unsuccessful domain name resolution”

The above message is a very common message caused by the local internet provider DNS resolution failure and cane be fixed very easily.

below is the error message that you may get when trying to connect to the VPN while connected to the home internet.

You will see that Cisco Anyconnect displays an error message where it is not able to connect to the VPN host using the hostname.

The first thing you will need to confirm is if the DNS resolution is working and in order to confirm that you will need to run the command prompt.

Launch the command prompt by going “start” “run” type “cmd” – see the screenshot for reference.

You can test the resolution by pinging espn.com.

type “ping” and you can see Ping espn.com is not resolving.
nslookup for cnn.com does not resolve and shows a loop back address as a dns server.

One good place to see more logs is by going to the gear icon on the Cisco Anyconnect. see the screenshot below for reference.

Go to the VPN tab and message history and you can see how many times, the client tried to connect and failed..

Start the command prompt again to test the DNS resolution.

This time use the DNS lookup using the google DNS server and you will see a response and that confirms that is the DNS server.

You can update the DNS server by manually adding the google DNS server for a temporary fix until your internet provider fixes the issue.

Thanks for ready this.
