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.

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

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

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).

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.

Hey,
there seams to be a solution:

A fix for KIA EU implemented in another app for reference:
Hyundai-Kia-Connect/hyundai_kia_connect_api@bb49831
