ACCESS DENIED on upload file Excel crypted by password

When I try to upload an excel crypted file I’ve this error:

|Fatal|webdav|OCA\DAV\Connector\Sabre\Exception\Forbidden: Access denied

  1. /var/www/html/nextcloud/apps/dav/lib/Connector/Sabre/Directory.php - line 156:OCA\DAV\Connector\Sabre\File->put(null)

I use the App “FLOW CONTROL” and when I disable it everything works fine.
I need to use this application because I have to forbid some extensions but more departements use the password with excel.

I’ve the same problem when I try to delete a crypted file. In this case the error is:

Fatal webdav OCP\Files\StorageAuthException: Storage unauthorized. /

and if I disabled “Flow Control” I don’t have any errors.

Any idea to work around?

Thank’s
