log in doesn't work – no results found

I’m trying to log in to one of my sites, soma1894.com, using two URLs:
https://www.soma1894.com/wordpress/wp-admin and
https://www.soma1894.com/wordpress/wp-login.php
and neither one works, both suddenly stopped working (and they used to just fine).

I’m getting this error message from both URLs:

“No Results Found

The page you requested could not be found. Try refining your search, or use the navigation above to locate the post.”

I don’t know why this is happening. Any help will be greatly appreciated, thanks. Lyle
