When we want to access our S3 library, we get this error:
<span style="color: #444444; font-family: 'Open Sans', sans-serif; font-size: 13px; line-height: 19.5px;">S3::getBucket(): [InvalidRequest] The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256. - /nas/content/live/embase/wp-content/plugins/wplms-s3/includes/class.s3.php:444 Code: 0</span>
what it wrong? Furthermore, WP wants to update your S3 addon even after updating. In other words, after updating, the update notice remains. What to do?
Make sure you are not using Frankfurt region buckets with WPLMS S3. It is the only region which uses version 4 of Amazon S3 API, whereas WPLMS S3 uses version 2.
p.s : Ignore the update notification, just match the version and do not update.
