I don't know what i missed but i am simply unable to connect to my Ds720+ with dsm 7.1.1-42962.
I'm not super experienced with FTP and stuff like that.
Im trying to do a simple mirror job from my PC to a shared folder in my NAS.
I entered my quick connect adress in "server name or IP adress" (is this the right thing i should write?)
Then used my quick connect ID and password.
Aslo tried the IP but im not exactly sure what is the right IP.

I get an error when i click "browse" to see my shared folders:
Is there a port i need to open or something i need to do elsewhere?!Cannot determine final path for "ftp://UrbanDownfall@QuickConnect.to/UrbanDownfall/~".
CURLE_OPERATION_TIMEDOUT: Failed to connect to QuickConnect.to port 21 after 11281 ms: Couldn't connect to server [curl_easy_perform]
Does the 2 step verification could block it?
Thanks so much in advance.
