404 Page Not Found error when loading forms

hi I just created a new form where I want vendors to apply in participating in a 2nd hand clothing sales. And everytime I go to preview the form it tells me 404 page not found. How come?

I have checked the form you have included in your post and was able to view it without any errors. Can you please check if you're still having any issues or if there is still any error message on your end as this appeared to be temporary?

Thank you.
