I've been using a DS218 for several years now to support backup. I've just configured a new NAS, DS220+, and I'm having problems connecting Synology Cloud Station Backup to my new NAS. I've mounted a remote folder from my NAS successfully on my PC so I know that the login is good. And I've been digging through the user permissions and can't seem to find anything. I've been Googling this topic and not coming up with a solution. Any hints?
