Hello,
I'm using WHMCS 8.1.1 and Plesk Obsidian 18.0.33. For quite awhile now, I have been unable to use the Login to Plesk Control Panel button from the Client Area. Instead, this redirects you to https://exampled-plesk-server:8443/login_up.php?success_redirect_url=%2Findex.php
Is this a known issue? If not, where can I start looking to fix it? Thanks in advance!
