Join_Ans delay due to HTTP integration fail

Hi, brocaar
we are working on loraserver and lora-app-server 1.0, everything run very well, but we found that failing in http integration endpoint will block the join server sending the join_Ans to loraserver, the join_accepet downlink will delay therefore, and then gateway can not catch up with the device’s window, finally device can’t join.

If the join http integration endpoint is running well, this will not happen.
Is it possible to ignore those http error or don’t let them affect the join_ans?

This change should fix the issue:

we have added your change to project, it works perfectly, thank you so much!
