404 Error when I use addon domain

I have 2 addon domain for my account.

First one is given by infinityfree but second one, I have created in Freenom website.
For second one(zjatkwkfy.ga) the namespaces are ns1.epizy.com and ns2.epizy.com

I have done setting namespaces and put my html file at location htdocs but whenever I try to access, it shows 404 error

Please tell me how to fix it

hi

it works for me (zjatkwkfy.ga)
but you miss the essential files that should be in these folders

js css img

clean browser cache CTRL + F5
then open browser dev. tools( F12) and look at the console
and put the necessary files in the appropriate folders
