I have recently enabled ssh session sharing on a host machine. My current ssh config file looks like this :

$ cat .ssh/config
Host *
CheckHostIP no
ForwardX11 yes
ControlMaster auto
ControlPath ~/.ssh/master-%r@%h:%p

After creating this ssh config file I can no longer browse a remote direcory using sftp protocol in Dolphin. 

Dolphin displays an error message box "Error encountered while talking to ssh" and the status message is set to "Connection failed"

Howver command line sftp/scp/ssh work perfectly fine hence there is no problem in my config file.
