Fabric connection to Azure Postgres server failing again

Attempting to validate connection credentials to a Azure PostgreSQL instance in our Azure tenant.

The report refreshes manually, but we cannot schedule a recurring refresh until this issue is resolved

This looks like a recurrance of an issue that occurred back in November of 2020

When connecting to data source uncheck the marked box. This should resolve the issue.
