Cannot access wordpress wp-admin page

Hi, For all my websites in the cyber panel, the home page is working fine. but whenever i want to access wp-admin to login into site, login is failing.

Even when trying to install a WordPress into new subdomain iam getting error as “unable to connect to the server”

Note: I also upgraded cyber panel to latest version , still the problem not got resolved.

Kindly help me to resolve this issue!
