We are working on a Replicate Entries task, which walks up to the edge of the cliff but never dives off.

We have a test rule as simple as it gets:

Looking at the WF Cache, the briefcase gets created but is never populated:

The problem is that the rule hangs up at this point and eventually (after 30 minutes) shows a warning, "Error reading HTTP response body".  Both servers are V11, one has WF 10.4, and the other has WF 11.  Neither has TLS 1.2 enabled

The logs show no other messages or warnings.

The account used in the connection profile is a domain account, and can log into both repos.  I even granted the service account full control to the WF Cache, but nothing makes a difference.  Is this as "simple" as turning on SSL?
