        @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 🎖
