No SSH or SFTP Access

Yesterday out of the blue my XBMC lost my zeroconfig to my macbook. As I was playing around I noticed I couldn´t even log in via SSH with ssh root@appletv ip

 

I get:

Stackmac:~ stacker$ ssh root@192.168.1.36
ssh: connect to host 192.168.1.36 port 22: Operation timed out
Stackmac:~ stacker$ 

I went and deleted all known hosts to see if that was the problem but still can´t access it. What could be causing this issue?

 

I can access SSH on the two others computers in the house, just not mine…

Same problem:

Simons-Mac:~ simon$ ssh -1 root@192.168.1.127

ssh: connect to host 192.168.1.127 port 22: Operation timed out

Simons-Mac:~ simon$ 

Haven’t been able to connect since installing the Plex client on OS 5 ATV2 Flash Black.
