linux - Error Putty X11 proxy: Authorisation not recognised

I'm developing a robot with a Raspberry Pi, and I'm having trouble with X11 forwarding. When I'm going to run my script as:

   sudo python myscript.py

I get the error:

   Putty X11 proxy: Authorisation not recognised
   (Imagen Combinada:3642) : Gtk-Warning **: cannot open display: localhost:10.0

I'm using PuTTY with Xming(Enabling SSH -> X11 -> Enable X11 Forwarding).

Does someone know what can be happening here and how could I solve it?
