PrivateLink Validation Error - When trying to access to Workspace

[ambigus9]

We have a workspace that had been deployed on AWS customer architecture using Terraform privatelink: https://registry.terraform.io/providers/databricks/databricks/latest/docs/guides/aws-private-link-wo...

The fact is when we disable the Public Access:

We are getting "login.html?error=private-link-validation-error"

We have the security group of Data Plane and Workspace configured as follows:

Data Plane Security Group - Inbound Rules:

Data Plane Security Group - Outbound Rules:

Workspaces Security Group - Inbound Rules:

Workspaces Security Group - Outbound Rules:

Any help will be appreciated
