OpenVPN setup problem

Hi, I’m running through the instructions for setting up openvpn on an ec2 instance in aws. While following the instructions from RAK.

ubuntu@ip-172-31-23-212:~$ sudo mkdir -p /etc/openvpn/easyrsa
ubuntu@ip-172-31-23-212:~$ tar zxvf easyrsa.tar.gz

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
ubuntu@ip-172-31-23-212:~$

I’m assuming the easyrsa.tar.gz is the issue?
I tried removing the “z” in case it wasn’t compressed, but same result.
Any assistance would be much appreciated.

Found the problem, the link has changed to easyrsa.
