      Description

      The description of this issue was copied from GUAC-1509, an issue in the JIRA instance used by the Guacamole project prior to its acceptance into the Apache Incubator.

      Comments, attachments, related issues, and history from prior to acceptance have not been copied and can be found instead at the original issue.

      If a connection is configured to have SFTP support for file transfers with VNC, and the SFTP server goes down or is not connectable for any reason, the system can not be accessed. The Home, Reconnect, Logout dialog is displayed.

      From the guacd log:
