Problem is google webmaster tools cant fetch my magento2 web site,

My backend settings,

I want to use secure base url so that reason I chanced base url as a https, but I think it doesn't matter because when I tried to fetch as google "http://" look like succeed but render says "This website temporarily unavailable."

I verified all domains at google webmaster, when I tired fetch as google for "https://" error is "Temporarily unreachable"

Any Ideas ?
