A common issue when trying to connect via FTP to a server is to receive a connection timeout or simply no files list from the remote server.
If you are seeing this then we suggest switching your file transfer mode in your FTP software, this changes the ports used by ftp and often resolves the issue. if you are currently set to Active then change to passive and if passive is set then try active.
Below is the Dreamweaver settings window and it uses active mode unless "Use passive ftp" is ticked, your ftp software may look different.
Still having issues then please contact support.
