Updated request/response pattern?

[Logopher]

Environment

NetMQ Version:    4.0.1.8
Operating System: Windows 10 IoT Enterprise LTSC
.NET Version:     6.0

Expected behaviour

Requests should appear in Wireshark when I watch the relevant port and be received by the other end, then responses should do the same.

Or, stepping back a bit, I'm having trouble building a request/response setup and I doubt it's actually a bug in NetMQ, but I think the documentation is lacking.

Actual behaviour

Requests are supposedly sent but do not appear in Wireshark and are not received on the other end.

Steps to reproduce the behaviour

I wouldn't mind copying the content over to here, but my instincts tell me it's better to leave it in one spot:
