I created a subdomain in Cloudflare. I did this by creating a new A record with the subdomain server. I had this led to the plesk server where I can log in. the subdomain works in the sense that I am being directed to the login page. As soon as I log in and I click on login I am redirected back to the login page and it seems as if nothing has happened. I can just log in via the ip address of the server but as soon as I do that via the subdomain I can’t do that anymore. anyone have any idea what I can do about this?
