Hmmm, that looks good, and proves that the keys in the node are okay too…
What LoRaWAN port are you using? You should not use port 0.
(It seems it’s port 0x63 or decimal 99, which should be fine. To be sure you can also paste a full LoRaWAN packet from the gateway’s Traffic page into an online decoder to see that.)
It seems your device is sending a DeviceTimeReq MAC Command, which is not supported yet. But I’d assume the payload would then still make it to the application.
Any error when you scroll down a bit further in the expanded uplink in TTN Console?
