No Schedule join-accept downlink after successfully processed join request!

I’m facing an issue with one of my node (mclimate CO2).
When node try to join, TTN accept join request, successfuly process it, but no dowlink “join-accept” is scheduled.

When I try to join with my Adeunis tester, I can see this downlink scheduling, but not when my device try to.

My MClimate Node:

Node is maybe to far from gateway, but I don’t unserstand why I can not see any downlink after join accept :confused:

Any Idea ?
