404 Not Found nginx on wp-admin

I have my own domain and I’m hosting the site on InfinityFree. So when typing http:// mysite.com/wp-admin it gives me 404 Not Found-nginx page.

I have installed WordPress successfully and also added a nameserver. I have changed nothing, just installed fresh and end up with this.

I don’t know what wrong? I’m creating the site for myself and still learning. I’ve read few articles but did not found the exact answer.

Thank You!
