It is was a known issue; see https://status.thethings.network/ (meanwhile resolved).

Asides: why does the screenshot show both EU_863_870 and CN_470_510? (Maybe fine for your region; I don’t know, but it looks weird.) And if you’re always sending data this often then beware of the LoRaWAN limitations.

Because I run two gateways, one is 470MHz and the other is 868MHz.
