Network error: connection refused after ForwardX11Trusted yes

Question

I have an ubuntu server with opencv and cmake installed. My idea was to configure it so each time i run a program on the server i get the results on my local OS (windows 7) through Xming.

This morning everything was going great, i executed a program and my local machine detected it and opened an empty window. On the server, the execution returned me this error "GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed". I looked over the internet and i read that i could try writting "ForwardX11Trusted yes" in the /etc/ssh/sshd_config file, so i did it.

Now i cannot access the server. Putty shows me the "Network error: connection refused". As im not able to access the server i cannot reverse the last changes...

What can i do? Is it normal to put "ForwardX11Trusted yes" and then not be able to ssh connect anymore??

Thank you in advance.

"Connection refused" suggests that the SSH server isn't running on the remote host. You may have failed to restart it properly, or there may be an error in sshd_config which prevented the server from restarting.
