Tesla (fleet api) Rejected

Hi!

I hope somebody can help me. I’ve spent days on this issue.

  1. I have set up a Tesla Developer account with all the credentials and added it to Home Assistant.
  2. I have the key on my server and it’s available.

I still get the problem - rejected by Tesla

Am I doing something wrong, or does anybody know how to fix (or verify) this?

Kind regards,
Sjoerd
