  • 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.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

    Hi Peter, Thank you for your response! On several websites we used Plesk to install a Let's Encrypt certificate. The SSL score on SSLLabs.com is A (good) and no issues are shown. However, Google does warn for a self-signed certificate. I've read all topics to find a solution. Advanced server...

    Issue Google thinks LetsEncrypt SSL certificate is "Self signed" - SNI - server default IP
