Video Background Home gone

Hello,

My video background in the home page disappeared.

Here the code:

[vc_row gmbt_prlx_bg_type=”video” gmbt_prlx_video=”https://www.youtube.com/watch?v=Gp6xh4hfN_4″ el_class=”overlay”][vc_column width=”1/12″][vc_column_text]
[/vc_column_text][/vc_column][vc_column width=”5/6″][vc_column_text remove_boxed=”Yes”]

I never changed it.
