“Xlib: PuTTY X11 proxy: wrong authentication protocol attempted” solution!

After wasting a couple hours I’ve found someone who had the solution, which I found through this guy’s blog.

In my case, what I had was a chroot jail inside a server (which I also had full control), here are the steps:

 

1. Connect to the server
2. Execute:

   # xauth list
   devserver/unix:10  MIT-MAGIC-COOKIE-1  f44098e4ee6687e163c152a72c7dacbd

   and copy the auth data;

3. Enter the chroot jail, and execute

   # xauth add devserver/unix:10  MIT-MAGIC-COOKIE-1  f44098e4ee6687e163c152a72c7dacbd

4. And thats it, It should be working now.
