I have the exact same problem. It is also preventing Deja Dup from backing up my files.
My server is on my local network, and I have also tried remote connecting from a friend's house, both fail with the same message after 10 minutes. In both situations, ssh and sshfs from the command line are successful with no problems or delays. "Error mounting location: DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." gvfs-mount ssh://user@myserver fails with the same message after 10 minutes. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/883746 Title: cannot connect to ssh server Status in “nautilus” package in Ubuntu: Incomplete Bug description: Using the "Connect To Server" GUI I cannot connect to an ssh host, after a long while I get "Timed out while logging in" error.
