2244 +Ensure that the Device Address (DevAddr) and the two keys match between the LT-22222-L and The Things Stack. You can modify them either in The Things Stack or on the LT-22222-L to make them align. In The Things Stack, you can configure the NwkSKey and AppSKey on the settings page, but note that the Device Address is generated by The Things Stack.
