      @Alanesi said in StrongSwan user authentication failed on Android:

      ignore candidate 'con-mobile' without matching IKE proposal

      Check the phase-1 settings on both sides of the tunnel . If the Windows client is working perfectly , it is possible that an error occurred in the Android client settings.

      P.S. I would recommend selecting the CA certificate manually in the client settings

        I did the manual selection for the CA. I'll see what else I can change.

              Then you need to check the settings of the Android client
              There may be an error in the username/password field

                          okay, on the android part there is not much more to todo.
                          Normally this is the easy part.

                          Now, I think it's time for pictures from your pfsense and android. but don't forget to deleted the sensitive Infos.

                                  Phase 1:
                                  Switch to:
                                  AES / 256 bits / SHA256 / 14 (2048 bit)
                                  and
                                  Enable MOBIKE

                                  Android:
                                  Don't forget the advanced settings (see above).

                                    THAT'S GREAT IT WORKED.
                                    I accualy added AES / 256 bits / SHA256 / 14 (2048 bit) to the current one.

                                    Thanks @Alitai 🎖
