FPN problems (Remote Delta Link)

55 Views

This time I need your help 😊

We have a federated portal, the consumer is running on SP18 and the producer on SP15.

On our producer we can view the application, it works perfectly.

We have created a Remote Delta Link on the consumer, but previewing the (copy of) remote delta link doesn't work. It generated an error:
