openvpn: crl has expired?
We have an OpenVPN in our aws setup which was set up by a client and now they are not able to connect to open vpn say "crl has expired" . We are trying to regenerate the crl but to do that we need to go to the easy-rsa folder and there I need to run following command:
- cd path/to/easy-rsa/directory
- here need to run the following command
./easy-rsa crl-gen
- but here the problem is the easy-rsa script file inside the easy-rsa directory is missing and without that we will not be able to generate the crl.

Can anyone please help me with this, This is a production server issue ?
Solution 1:
easy-rsa is packaged already for most Linux distributions. Just install it from your package manager.
For example:
sudo apt install easy-rsa
You should run easy-rsa installed from your distribution packages as easy-rsa, not ./easy-rsa.
Solution 2:
Download the easy-rsa script again, create a new crl.
Solution 3:
When you generate a new CRL file at the server to move to the client, use a longer time period with this command (10 years): EASYRSA_CRL_DAYS=3650 ./easyrsa gen-crl. For me, I use the script download from their latest release.
