As title,
Lish is not working anymore on my linode, there is no way to connect to lish using SSH or the Ajax console.

I have just opened a ticket and waiting for an answer, I opened the thread just to know
if this is a diffused problem or a problem that is afflicting mine VPS only.

Have you seen https://blog.linode.com/2013/04/30/lish-ssh-gateway/ ?
