Panel + views + taxonomy depth problem following this tutorial I create a Panel Page for the taxonomy term to display all the content related to the taxonomy term and it works.  

But I need to have in all the nodes related to the taxonomy terms in the url and children.
So I sobstitute taxonomy term ID contex filter with taxonomy term ID (with depth) and do not work anymore -.-   

This is the contex filter's setting   

If I try this view block in view page [putting 'taxonomy-name' as argument] it works but not in the panel page.
Where is my mistake? 

I don't know if this can help. This is the contex of panel page [I setup the view to take argument from URL.. but maybe it can help]
You should try to add a "Content pane" display on the view instead of using a page display (enable "Views content panes" module). "Content pane" allows to set the argument input from the views settings. On the "argument input" you can select "From context" as source, and the required term context.

EDIT: Like I've wrote on the following comments, the correct contextual filter settings is:

1) Content: Has taxonomy term ID (with depth). Provide a default value: Taxonomy term ID from URL (Load default filter from term page). Specify validation criteria: Taxonomy term, Filter value type: Term ID

2) Content: Has taxonomy term ID depth modifier
