Yes, please keep us updated. What are "other" receivers that work? Obviously they are aware of the special formatting of the data.
Can you point us to a website describing the sender? (NI also has a product with "MAX" in the name, so it helps to be very specific :))

Hello,
I am also not receiving information using Simple UDP - receiver example.
I am currently sending information to an ESP8266 on UDP using the Simple UDP - sender example. I know that the message arrives, because i have the ESP connected to the PC on the serial port and it sends confirmation on the serial monitor.
But the answer is not coming back to Simple UDP - receiver.
If i use Packet sender, the packet sender sends and also receives the message from the ESP.
Labview Simple UDP receiver works if i only send information from the localhost to the localhost, but i need to send the information from the ESP8266.
I attached the sender VI, a picture with the Serial Monitor with the package arrival confirmation and a screen shot with the Packet sender.
I do not use packet sender in the same time with labview to avoid conflict on port.
I also disabled the firewall.
I am using labview 2015 x86 and laptop with windows 10 and only wifi connected.
Any idea?
Thanks!

Sigh. You continue to feed us little dribbles and drabs of information, and then ask "Why doesn't this work?". Here's what you should do:
The LabVIEW UDP VIs work correctly when "used as directed" (and when the Sender is sending meaningful data). Your use of a third-party Packet Sender suggests that (a) your device might be sending meaningful packets, or (b) Packet Sender is smart enough to "interpret" what it gets so that it makes sense. Something isn't working, we're not there to trouble-shoot, and I'm not sure we "know enough" from you to make meaningful guesses.
However, Altenbach has an uncanny way of sleuthing out the culprit even without much help from the Original Poster ... [I'm not as talented, nor, I fear, as patient].

Hi.
Thanks for helping.
I found the problem. I was sending information to ESP8266 and the ESP was replying on the same port that the information came from. But in LAbview UDP receiver i could not use the same port because, the port was used by the Labview UDP sender...
I changed the port in the EPS and in the Receiver and is working now.
Have a nice day!
