ClientError http 418, message="I'm a teapot"

[geertmeersman]

Hi Rene,

I can't seem to log in anymore and am receiving a http 418 error. The mobile app still seems to work fine.

Hi, I see this too. Looks like MB changed something in their backends. Let me check.

[ReneNulschDE]

Master branch code should work again for Europe. Make sure you open the mobile app and agree to the new data protection rules.

I'll try to test the other regions and publish a new version soon.

[SuperMasterPhoenix]

Works again for EU using master branch. Thank you for this quick fix!

[ReneNulschDE]

Non EU endpoints are fixed too.

Hello, where can I confirm the new data protection rules? I also have no connection and then I deleted the integration and added it again. Now when I enter the email address it says "Unknown Error occured" and in the logs it says "I'm a teapot".

i did exactly the same and have now the "Unknown Error occured". I confirmed the new data protection rules in the Mercedes ME APP on my android. But it fixed nothing.

[ReneNulschDE]

Please read my comments. You have to update the code based on the latest master branch or wait for the release. I'm just typing the release notes...

[kilian-f-za]

Thank you. New version is there and works. Thanks for the quick support.

Solved with v0.9.8
