No connection to UI - please help!

hello all together:

my mycloud is at a server center out of my home. i have total access to FTP and can connect via WD my cloud desktop app. BUT: I can’t connect to the UI. What could be the problem? What did i have to change? What can i do?

Another Question is: How can i send a downloadlink to a friend (like dropbox) that he can download the file or folder WITHOUT! having an account on mycloud. That would be much more easy!

thanks a lot for help!
