The SFTP support within RDP will *not* automatically assume any parameters - that is, if you leave hostname blank, it isn't going to just use the hostname of the RDP server. It needs a hostname. Same for username and password. If you have filled those in and are still seeing connection issues, you may be running into this issue: https://issues.apache.org/jira/browse/GUACAMOLE-1140 -Nick
