<p>The bucket you're trying to list is probably in the Frankfurt S3 region. The 3rd party library used in Craft 2.x for Amazon S3 support does not support Signature Version 4 that Frankfurt region requires, so you won't be able to use buckets in that region, as outlined <a href="https://craftcms.stackexchange.com/questions/5437/errors-occuring-with-assets-and-amazon-s3">in this answer</a></p>

<p>Craft 3.0 will not have this limitation, however.</p>

<p>Nope.  There are no limitations when running Craft on a <a href="https://craftcms.com/support/license-enforcement#how-do-we-determine-craft-is-running-on-a-public-domain" rel="nofollow noreferrer">"non-public"</a> domain in trial mode.</p>

<p>Check your browser's console and see if it's logging any errors.  My guess is you'll see a 500 Internal Server Error and the underlying error message will be logged into <code>craft/storage/runtime/logs</code>.</p>

<p>I am using the Craft Pro trial version and I want to use S3 for my Assets.  However, I enter my credentials but the refresh button does not show my bucket.  Also, when I try the refresh with wrong credentials it shows the error message but with correct it just doesn't show anything. I tried to connect to by bucket with other tools and was successful so this is why am thinking that is a restriction on the trial version of Pro.</p>

<p>So is it a Craft trial issue? Are you allowed to connect to S3 in trial version of Craft Pro?</p>

I am using the Craft Pro trial version and I want to use S3 for my Assets. However, I enter my credentials but the refresh button does not show my bucket. Also, when I try the refresh with wrong credentials it shows the error message but with correct it just doesn't show anything. I tried to connect to by bucket with other tools and was successful so this is why am thinking that is a restriction on the trial version of Pro.

So is it a Craft trial issue? Are you allowed to connect to S3 in trial version of Craft Pro?

The bucket you're trying to list is probably in the Frankfurt S3 region. The 3rd party library used in Craft 2.x for Amazon S3 support does not support Signature Version 4 that Frankfurt region requires, so you won't be able to use buckets in that region, as outlined [in this answer](https://craftcms.stackexchange.com/questions/5437/errors-occuring-with-assets-and-amazon-s3)

Nope. There are no limitations when running Craft on a ["non-public"](https://craftcms.com/support/license-enforcement#how-do-we-determine-craft-is-running-on-a-public-domain) domain in trial mode.

> However, I enter my credentials but the refresh button does not show my bucket.

Check your browser's console and see if it's logging any errors. My guess is you'll see a 500 Internal Server Error and the underlying error message will be logged into `craft/storage/runtime/logs`.
