Transport-level Error using Dataflows Gen2

I have every reason to believe that the dataflow-warehouse connnection is still unstable after seeing similar issues, though in my case, everything is located in the same Fabric workspace. The gateway version I am using is 3000.182.5.

- When I set a warehouse as my data destination, the dataflow refresh will fail with the transport level error, but not when I use a lakehouse destination. My source data is coming from another lakehouse in the workspace.

- In my warehouse, I have a table in a schema other dbo. That table no longer appears on the navigation pane even though no one has touched it. When I click to refresh the tables folder, I get an error declaring "we couldn't get your warehouse's updated schema'. But when I try to set the data destination in a dataflow, the wizard shows that table.
