LoPy Issue Connecting To Gateway with OTAA

[az311]

Hello all,

I have been running into an issue connecting my LoPy to a Multitech Gateway. EUI and Key match and what's really puzzling me that the gateway recognize the request to join from the LoPy node, but for some reason LoPy never finishes the handshake process and continue trying to connect as shown in the picture in the link below.

I'm running the latest firmware and using the example code 5.3.2.

Any help would be much much appreciated.
