Join Server Error : join-request to join-server error


I am trying to develop a join server linked to an HSM.
I have configured the endpoint of the join server and I am receiving the JoinReqs.

But the chirpstack-network-server isn’t receiving my JoinAns.

i have error logs :

level = error msg = “uplink: processing uplink frame error” ctx_id = 2c0dd4fe-6046-4af4-a94b-f24b887a55da error = “join-request to join-server error: response error, code:, description:”

this log isn’t very explicit :confused:

Somebody can help me ?

Sombody here can help me to find where is my problem ?

It looks like your join-server does not return the response in the expected format:

If ans.Result.ResultCode != Success is not equal to Success, then it is assumed that the request failed. The error and description is taken from the response body, but if that is empty too then you get the above error.

Thanks Brocaar,

i found where was my mistake .
Now, i see JoinAccept trame in chirpstack Gateway.
In my device, i find Device address and Network session key in Activation Tab. But Application session key is empty …

Do you have an idea where is the problem ?

in addition, i have an error ==> “get device-session error: object does not exist”
