@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

Alanesi · Aug 8, 2020, 12:19 PM

@Konstanti

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

Konstanti · Aug 8, 2020, 12:28 PM

@Alanesi

The user [user@domain.com] created ?

@Konstanti

Yes, and its working on windows

Konstanti · Aug 8, 2020, 2:07 PM

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

Unfortunately still the same issue but with different log

do you have set dns sec on your android?

Alanesi · Aug 9, 2020, 9:09 AM

@Alitai

No, but to wich server?

Alitai · Aug 9, 2020, 1:46 PM

okay, did you set the user identity under advance settings on the strongswan app?

Alanesi · Aug 9, 2020, 1:46 PM

@Alitai
Yes its the same username.

Alitai · Aug 9, 2020, 2:35 PM

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.

Alanesi · Aug 12, 2020, 7:25 AM

@Alitai
This the P1 on pfSense.

This Mobile Client

For the Pre-Shared Keys the secret type is EAP.

This P2

This on the Andriod

Konstanti · Aug 12, 2020, 8:47 AM

@Alanesi
Phase 1 - My identifier

Alanesi · Aug 12, 2020, 4:13 PM

Thanks @Konstanti

I did that but it didnt make any diffreance still same error.

Alitai · Aug 12, 2020, 4:24 PM

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

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

Alanesi · Aug 12, 2020, 6:08 PM

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

Thanks @Alitai
