Most Cloudstorage errors are logged with an empty string as:
Code:
05/02/22-19:02:01 ERROR CloudStorage:
but some are reported as
Code:
05/02/22-19:46:47 ERROR CloudStorage: 500 'EPSV': command unrecognized.
Since EPSV seems to be FTP-related, I assume that the first ones were triggered for some Webdav servers and the second ones for an FTP server.
