XQuartz error on ssh connection

Question

I'm connected to a remote Linux server via ssh, and I'm trying to execute ImageMagick's display command. I know that the problem is probably not on the server side, because when I connect from different machines I don't get the same problem. And I installed XQuartz on my local machine as well as connected using the ssh tags -Y and -X (neither fix the problem) and I'm still getting the following error. My computer is a MacBook Pro running El Capitan. Any idea?

display: unable to open X server `' @ error/display.c/DisplayImageCommand/426.

Thanks!

I think the trick is to start XQuartz in the background on your Mac before you do anything and allow remote machines to connect.

So, on your Mac, in Terminal, start XQuartz:

X &

Now right-click the XQuartz icon in your Dock and click:

Applications -> Terminal

and in the Terminal that appears, type:

xhost +

Later, when you have it working, tighten up the security on the xhost command by being a bit more specific with IP addresses.

Unforunately, I get the same problem here. When I type in "xhost +" I get – awerchniak Oct 24 '16 at 11:36
xhost: unable to open display "" – awerchniak Oct 24 '16 at 11:37
And when I try to call the display command, I get the same error as above – awerchniak Oct 24 '16 at 11:37
