Thanks for all the details provided.
From what we can see in the screenshots, these error messages seem to be happening from the AWS side. ORCID API is not receiving these requests.
However, we've done some research about this and the "502 error" message seems to be an issue regarding the SSL/TLS negotiation. The second "Access denied" error seems to be an issue with the bucket policy on your AWS settings.
Please, check out these resources that you might find useful here:

I hope that this information is useful and you're able to fix it. In any case, we'll be waiting for your updates on this.
