Can't get to login page

So I started working on a site from where the previous developer left. The thing is, I can’t get to the wordpress login page. The previous dev changed it to https://asifmohiuddin.com/probesh from the regular https://asifmohiuddin.com/wp-admin using “Better WP Security” but it hasn’t been working since the site was moved to another host as a parked domain.

I do, however, have access to the host server, so if any file requires any change I will be able to do that.

Any help will be much appreciated.
