Backup Add Storage Location - EOF error

Hi,
I found a problem when trying to add a s3 backup storage location on PMM server UI.

The bucket I want to configure is a DigitalOcean space. After putting all the configs on UI and press “Test”, the EOF error appears.

Endpoint: https://myspace.ams3.digitaloceanspaces.com (myspace is the name of the space)
Bucket Name: backup (folder created inside the space)
Access Key: **
Secret Key: **

Hoping for some help!
