  • 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.

Does that still work? I am testing the CloudLinux AWS offering and it has this problem.
I was able to fix it by using local VPC 10.0.0.x IP address, but the CL version works differently.
CL is telling me they wont support the AWS instance they offer, so I am wondering if anyone else has figured this out?
 
That is the problem that I'm interested.
Is there any update on my issue? It seems like the integration of Elastic IP with Plesk is causing this problem. I think a minor configuration change can make my favourite panel up and running on the cloud.
