Error when adding second client cert

[vitotol]

hello, I have an openvpn server and I had created a client cert for connecting on the VPN.
with client cert I can connect with no issues on server,

the ovpn file looks like this:
# the name set when creating certificate for server
client
ca ca.crt
cert client.crt
key client.key


I recently needed to add another client too so I run the below commands:
source ./vars
./build-key client2

in keys file the below files created:
client2.crt
client2.csr
client2.key

I created another ovpn file that looks like that:
# the name set when creating certificate for server
client2
ca ca.crt
cert client2.crt
key client2.key

Unfortunately I cannot connect with client2, I get the below error:
OpenVPNClient start client2_p0092: process started and then immediately exited: []

With client I still can connect with no issues.

What should be the problem?

Thank you guys for your help in advance

sounds like a different topic, splitting.

As for the error, which version of the openvpn client is this?
