Hello @Jan Rigsinger,
Thank you for connecting offline to check the issue.
The issue you were facing occurred because your tenant was identified as one of the CDX tenant which caused it to be blocked. To resolve this, we reached out to the Product Group team internally. They have since unblocked your tenant, and please check and confirm, if you are able to access it successfully or not.
I hope this information is helpful. Please feel free to reach out if you have any further questions.
