Installed WordPress, Removed old index.html, but still opens the old website

Hello,

I installed wordpress on my hosting through Directadminto the root directory. So i can access admin panel by enterin https://www.agta.az/wp-admin
however, when you enter the domain https://www.agta.az it still opens the old website, though I have removed the idnex.html file. Can anyone help me?

Thanks!
