    We had to stop our server and our pfsense due to a power outage.
    When we restarted them, we could not login to OpenVPN anymore.

    In pfsense, I get an error message: "One or more of the selected Data Encryption Algorithms is not valid"

    How is it possible to fix the problem? I have the 2.7.0 version of pfsense and the 2.6.10-I003 version of OpenVPN.
    Thanks for your help

      @alanvpn

      The fastest way out :
      Your using (dealing with) security sensitive stuff : OpenVPN.
      Yet, you're way behind with your versions.
      ( you don't want to deal with an old version of the server and a recent openvpn client, or the other way around )

      Read this one first : [https://forum.netgate.com/category/34/openvpn](link url) : the very first pinned post.

      Step 1 : don't keep ancient OpenVPN stuff0. pfSense 2.7.0 isn't the latest version, get 2.7.2. This will contain a more recent version of pfSense.

      Make your OpenVPN server settings look like this :

      Also upgrade your OpenVPN client ( ! ).

      Now, from pfSense, re export the OpenVPN client settings to your device.
      Enjoy.

      No "help me" PM's please. Use the forum, the community will thank you.
      Edit : and where are the logs ??

        Thanks for your answer.

        The thing is that I don't have any option available in "Data Encrytption Algorithms" , "Fallback Data Encyption Algorithm" & "Auth digest algorithm". My 3 errors message certainly are for my 3 algorithms as in the picture below. Don't get why they are not valid anymore while it was ok before...
