# 53624: Public key credentials for media tracks encryption could not be loaded

Log Level: WARNING

## Description

The public key credentials configured in your account's composition settings could not be loaded.

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

### Possible causes

* If you have specified a public key to cryptographically protect media tracks, this is most likely due to the fact that the credentials resource has been removed from Twilio.

### Possible solutions

* In the composition settings section of your account's console, create and assign a new valid public key or disable the encryption (media will be uploaded in raw).
