# 53615: Access denied to external S3 bucket configured in recording settings

Log Level: WARNING

## Description

We failed to upload media to the external S3 bucket configured in your account's recording settings.

The media will not be uploaded until the configuration has been fixed.

### Possible causes

This is a configuration error that can have different root causes

* The IAM user referenced in the credentials provided does not have enough permissions to upload to the bucket.
* The bucket configured in your settings has SSE-S3 enabled. The only default encryption mechanism supported is SSE-KMS. Please review the guides for more informtion

### Possible solutions

* In the recording settings section of your account's console, review the credentials for accessing your S3 bucket or disable the external storage (media will be uploaded to the default bucket).
* If SSE-S3 is enabled, please consider switching to SSE-KMS.
