What does \Request failed with status code 400\" means?"

Good day @Antje_Toplek,

First, I wanted to give you a warm welcome to the Personio Community 🎉.

I have investigated and my colleagues from the support team have informed me that this topic might be related to a current system error. Since it would be necessary to investigate thoroughly and login to your account, I would kindly ask you to contact my colleagues from the support team via Find Answers.  My colleagues will be able to log in into your account and check the settings together with you.

Be aware that only Contract and Account owners can contact our support team. In case you are not registered as such, please contact your colleagues in the role, or add this information in your account. You can find out how here.

Please let me know if there is anything else I can support you with.

I wish you a lovely day.
