I dont want redirection

so i made a website with wordpress .
the address is samid.000webhostapp.com
i bought a domain and parked it and its fine.
but there is a problem . instead of going to my domain samid.ir
it redirects to samid.000webhostapp.com

I DONT WANT IT TO BE LIKE THIS
i want to go to this domain (samid.ir) and use my website

help please

Make sure you have not set any redirection in your account settings or in your .htaccess file.

how should i do that?

Short Version

i want to delete samid.000webhostapp.com
and just use the .ir domain that i bought
HELP

You cannot delete your 000webhostapp link, just don’t give it out.
