Redirect “must be logged in” link to custom login page

Friends, how can I change the link of the “you must be logged in to comment” message in Discussions / Comments area to my site’s custom login page? By default that link takes the user to WordPress login page.

Redirect plugins did not work, perhaps, the link looks like this: https://www.freelogica.kz/wp-login.php?redirect_to=https%3A%2F%2Fwww.freelogica.kz%2Fchto-takoe-freelogica%2F

Instead of that I would like it take to this page https://www.freelogica.kz/login/

I am using Ultimate Member plugin to manage subscriptions, and wpDiscuz to manage Discussion / Comments forms.

Thank you very much,
Dav.

The page I need help with: [log in to see the link]
