I solved the issue by migrating everything to S3 but you might want to look into this regardless.

The hostname defined inc/class-destination-s3.php is correct (and it’s not editable). Based on the error message and after doing a quick search in the plugin source code, the only library that could’ve generated the {service}.{region}.amazonaws.com URL is the AWS PHP SDK. Did you update it recently?

The fix is a simple as:

$action = isset($_GET['action']) ? $_GET['action'] : null;
if ( !get_site_option( 'dm_remote_login' ) || $action == 'logout' || isset( $_GET[ 'loggedout' ] ) ) {
    return false;
}

Do you mind checking that into SVN, Ron?

Also, I find the lack of development activity on this plugin a bit worrying. Any plans on releasing a new stable version soon that is guaranteed to work seamlessly with WP 4.0?
