I am a brand new user and was experiencing the same problem. I performed many of the same steps you did to no avail. But, I just figured it out. Here's what I did. I simply went into "Setup" and clicked on "Inputs" and added the source IP into the space where it says 255.255.255.255 and clicked "Add" and it started working. The Help File is misleading in that it says it should work by default, which is not the case here. I hope that helps.
