I get this error but it doesn't happen every time. See session log below.

Relevant port is open both ways. Since iperf is the network utility and relies on open ports, it should say in the error message what port is expected to be open and isn't, what protocol, etc. Give the user relevant information to be able to understand the failure and not ask too many questions.
