      Good morning,
      we have a strange behavior in the OpenVPN connection.
      We have two computer configured in the same way (virtual machine cloned from the same master), with the same profile of connection and two different user (configured in the same way) that need to connect to a remote site.
      One of the two machine have no problem at all, the other one have some problem with timeout inactivity (the two user have the same use of connection) and a lot of problem with reconnection when he as shut down ( TLS handshake failed ).

      On the PC with the problem the user can have the disconnections randomly 3 time in a morning or have no issue for 2 days without change in the server side and in the client configuration.

      Here we have the log client side
