VERIFY ERROR



  • Hi all,
    I'm trying to setup OpenVPN from a windows client to my pfsense box, but I'm having some troubles with the verification phase:

    as you can see there is a VERIFY ERROR, that is something I have never seen in other pfsense openvpns I've set up in the same identical way. However, what I've done is:

    
       ./clean-all
       ./build-ca
       ./build-dh
       ./build-key-server myserver
       ./build-key user
    
    

    and then copied the user key and certificate and the server certificate into the client configuration.
    The same client from the same computer to another pfsense box configured the same way works fine without a problem. Any idea or clue on what to search for solving the problem?



  • Don't use the server certificate in the client configuration, use the certificate of the CA that signed the server cert which in your case is the same ca.crt that you used on the server.



  • Thanks, I had mess up the certificates! Now it works.
