Not able to download any document


I’ve found Alpaca via internet and would like to try it out. However, I am not able to download any document. For example:

When I try to update my subscription, you ask me to agree to the CTA and UTP Agreements. I can click on that and a new tab in Chrome (or Edge) occurs with following Text:
{“message”: “forbidden.”}

Request URL:
Request Method: GET
Status Code: 403 Forbidden
Referrer Policy: strict-origin-when-cross-origin

I have the same problem when I try to get a live trading account. There I would like to download and read the documents before I agree to them.

Best Regards,
