Client cannot connect to server. Try to check your network configuration to find
out what the problem might be.

>  Another weired thing is that in my *destination host* , in this docker server is not running. Only the client shows up after typing docker version. It also shows /cannot connect to docker daemon. is <http://daemon.is> docker running in the host?/ However a few hours earlier it did not showd this message. there was a docker server  as well as the client.  *I dont know what happened with my docker!!! As well as I cant migrate. *
