When you keep store closed then bots hitting this kind of Url and logging 404 error
Its completely new & closed store with multi-language
log that found as below
Error 404. The requested page (/en/page-not-found/storeclosed) was not found
Even same kind of problem I found in one of the live store where it makes category/product url like
"getFilteredProducts" is should not come in any of the product or category page Url. This method "getFilteredProducts" used by nop-templates Ajax filter plugin.
