  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.
  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.

Issue Plesk blocks localhost connection

New Pleskian
I have noticed on WordPress sites, it states System Heath needs to be improved. Loopbacks are being blocked. I do have Firewall enabled, WAF and Fail2ban. I don't see any errors in the logs that I can find. Any suggestions would be appreciated.

CentOS 8
