…and from the same topic quoted above, for another device than yours:

Looking around at Antratek found that the prescription was not correct and that you should ask for a valid AppKey for your sensor. Antratek responded verry fast with a valid AppKey. That dit the trick.

Anyway, you can use the online decoder to check; you know that the gateway is receiving the Join Requests, so for troubleshooting there is no need to wait for another Join Request to be sent by the device. Just ensure that the online decoder shows that the MIC is valid and then you know which value for the AppKey to configure in TTN Console.
