Never redirected to WP login

Looks like that’s not a WordPress site, rather a site created with GoDaddy’s “Instapage” tool.

I can see a login link which takes you here.

Yes, unfortunately it only takes me to my GoDaddy hosting account, not the WordPress account… There’s definitely a way to do it as i’ve done it before, I just can’t remember how…

Check if your hosting company has blocked (in .htaccess) access to wp-login.php.

because of this issues: https://codex.www.ads-software.com/Brute_Force_Attacks providers have taken steps to prevent this.

If you have ftp access to your site you can check the .htaccess for lines like below:

# Block access to wp-admin.
order deny,allow
allow from x.x.x.x
deny from all

(where x.x.x.x would be an ip-address)
