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. Chrome macbook m1.

You can test the resolution by pinging espn.com.

1. type 'ping' and you can see Ping espn.com is not resolving.
2. 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.

Problem

You are trying to connect to MIT's VPN on vpn.mit.edu, but get an error:

The VPN connection failed due to unsuccessful domain name resolution.

Solution

First, make sure that the problem only affects the Cisco VPN app. Test vpn.mit.edu with other tools such as a web browser, or 'ping' the hostname.

The cause is not fully known, but this is seen more frequently when people are using Google Public DNS (DNS servers 8.8.8.8 and 8.8.4.4)

• Try using another DNS server, such as your ISP's DNS server
• Try sending some pings to vpn.mit.edu before connecting; these can help cache the IP address in your DNS cache.
• Wait a few minutes and try connecting again; the connection can work if you try again later.
