Chirpstack not returning JoinAccept

[haimiko]

I'm running OTAA join requests on Chirpstack. I'm seeing JoinRequest on Chirpstack but never a JoinAccept. Usually this means the App key is incorrect but I'm not seeing this as the case.

My device.json

{
    "Device": {
        "JoinEUI": "ded70e37a48e4289",
        "DevEUI": "ded70e37a48e4289"
    },
    "RootKeys": {
        "AppKey": "1CB94D4B9B5522C11233D2EEFE64D82A",
        "NwkKey": "1CB94D4B9B5522C11233D2EEFE64D82A"
    }
}

My join request:

#mote join  -n

I'm getting the following error on the app server:

Suggestions?

Hi @haimiko ,
The problem you mentioned may probably be caused by the mismatch of DevAddr.
It is suggested to perform the following three steps to check it out:

1. Whether the gateway is registered before;
2. mote pull before JOIN;
3. Check out on the ChirpStack website whether the JoinReq message has been recieved.

Tried the pull, made no difference. Tried recreating the device as well. JoinReq message has been received by the Chirpstack website, not getting JoinAccept because the "security context is out of sync".

Ok for some reason now i'm receiving a JoinAccept

DevAddr matches the DevAddr in Chirpstack, but when I try to send data I get MIC errors:

And this is what shows up in Chirpstack
