OpenVPN CRL has expired
VERIFY ERROR: depth=0, error=CRL has expired: CN=servername
In order to fix the issue, we just need to recreate the crl.pem file.
we need to backup the current crl.pem file before creating a new one.
The location of the crl.pem file at /etc/openvpn/
#mv crl.pem crl.pem.back
Now go to easy-rsa folder
# cd easy-rsa
now generate crl.pem
# ./easyrsa gen–crl
Now copy the new crl.pem to openvpn folder
# cp –pr /etc/openvpn/easy–rsa/pki/crl.pem
Now restart openvpn service
