UnauthorizedAccess is not currently a documented error code in the standard (global) S3 documentation.
However, I did find a reference to it on the AWS help forum. If you are using AWS China (Beijing) this is likely the explanation.
In accordance with Chinese law and regulations, if you use AWS (China) to host a website providing non-commercial Internet information services, you must undertake filing procedures for a non-commercial website (an “ICP Recordal”) at the relevant government authority. If you use AWS (China) to host a website providing commercial Internet information services, you must obtain a value-added telecommunications license for a commercial website (an “ICP License”) from the relevant government authority. We may require you to produce your ICP Recordal or ICP License, as applicable, before you use AWS (China) to host public content.

The following is a Google translation from the actual Chinese documentation.
The following Amazon S3 features are either unavailable in the Beijing region or require an ICP license:
Amazon S3 objects honor anonymous GET requests only if the object owner’s Amazon AWS account is associated with a valid ICP license. As a result, hosting a static website from an Amazon S3 bucket and using pre-signed URLs require an ICP license.
http://docs.amazonaws.cn/aws/latest/userguide/s3.html (translated)
This implies that may only be able to access your content using the Authorization: header mechanism permitted in Signature Version 4, since the older Signature Version 2 is also not supported in China, or any other S3 region that launched in 2014 or later.

I met the same "UnauthorizedAccess" error recently in AWS (China).
As Michael already mentioned. "The following Amazon S3 features are either unavailable in the Beijing region or require an ICP license:
Amazon S3 objects honor anonymous GET requests only if the object owner’s Amazon AWS account is associated with a valid ICP license. As a result, hosting a static website from an Amazon S3 bucket and using pre-signed URLs require an ICP license."
After associated our ICP license with the AWS account, ports 80, 443, 8080 open and s3 pre-signed URLs work.
