I have an OTAA and downlink issue:
Every now and than I have the problem that I cannot get a join accept from the network.
It happens to multiple devices. Both self made and using RN2483 and commerical like the xignal mouse trap.
I do receive a good OTAA join request in my application but the device never receives a join accept.
When this happens I see always that the strongest gateways, that shall be selected to send join accept, have no gateway-id: (See below)

It is an intermitting fault that has happend several times over the last weeks (may be months).
In slack I raised the same question in OPS (https://thethingsnetwork.slack.com/archives/C1Q5XLNDT/p1571680789040000) and the responces make clear that we have a serious issue that is real.
Who else has this issue? Please comment your observations on this topic to get a good overview of the issue and indication of the size. Thanks.
My question to TTN or TTI is to look in to this issue and solve it.
