Goodmorning,

Also here i have the problem [2025-08-02 04:40:35] error: @EuropeController.login: sign in with EuropeanBrandAuthStrategy failed with error Error: @EuropeanBrandAuthStrategy.login: Authentication failed, cannot retrieve error message

i'm also on EU

Anybody has the official Bluelink mobile app could check that it is working or not working? This would help discriminate an issue on Hyundai's side or on bluelinky's side.

I am working on it this weekend. Hopefully fixed soon.

[dirkjanfaber]

Any update on the progress or something that can be tested already?

Btw I am using on Kia, which suffers the same problem.

[kelyaenn]

It’s working again for me since yesterday evening without any change in the code

[gerwim]

Can confirm. It worked yesterday evening at 21:00 (CEST).

[dirkjanfaber]

Super nice that it works again for some accounts. However, for Kia it isn't working (yet):

[2025-08-05 08:31:01] error: @EuropeController.login: sign in with EuropeanBrandAuthStrategy failed with error HTTPError: Response code 401 (Unauthorized)

Tried with 2 different cars / accounts that used to work without problems.

I've the same issue with kia eu bluelinky version 0.0.30 is already updated to 0.0.32

[cheick66]

Hey, there seams to be a solution:

A fix for KIA EU implemented in another app for reference: https://github.com/Hyundai-Kia-Connect/hyundai_kia_connect_api/commit/bb498310206a44cdab029aca8dfc5c92c208f80a

Not for Hyundai (you need to use bluelinky v9 it seems). Check last comments on PR #300.

FYI I am running off master using the debug.ts script and I am also running into the Invalid values error. It is preceded by this one:

@EuropeController.login: sign in with EuropeanBrandAuthStrategy failed with error Error: @EuropeanBrandAuthStrategy.login: Could not extract authorization code from redirect location:

https://idpconnect-eu.hyundai.com/auth/api/v2/user/oauth2/authorize?client_id=6d477c38-3ca4-4cf3-9557-2a1929a94654&redirect_uri=https://prd.eu-ccapi.hyundai.com:8080/api/v1/user/oauth2/redirect&nonce&state=ccsp&scope&response_type=code&connector_client_id=6d477c38-3ca4-4cf3-9557-2a1929a94654&connector_scope&orgHmgSid=&connector_session_key=…&captcha=1&reqUsername=…@…

The URL mentions captcha which makes me think this might be related to #307 which also mentions it.

I'm having the same problem, getting the same type of error.

I tried following the conversations in an issue over att Hyundai-Kia-Connect repo, in particular this comment. While I was eventually able to retrieve a token, I could not simply paste it as password to bluelinky. Either I'm doing something wrong or bluelinky does not work the same way as the python library does.
