Cert not being sent as part of http request

We found our issue.

We were disabling hostname verification, but apparently that was causing an issue with the cert being sent out.

So adding hostname verification fixed the issue.

Hi,

Can you provide full error log which shows error 400 and error output "No required SSL certificate was sent"?

Best regards,

Thanks.

We verified a supported cipher is being used. For some reason the cert is not being sent out

Hi,

The list of supported cipher suites can be found on nRF9160 Product Download webpage. You can also look at Limitations.

Best regards,

Where can I find the cipher suites that are supported in modem fw 1.3.6?

Yes, we are using socket offloading and get the same result using nrf_socket() and nrf_send()

We wrote a python script that uses the same cert/key and are able to sent the same message to the host/port that the nrf9160 is using and we receive a `200 OK` response from there, so i know the cert/key is good.

On the nrf9160 we are writing the cert/ket to the modem at a sec tag location, and then using the socket options I originally posted, and passing that sec tag to the `TLS_SEC_TAG_LIST` setsocopt() trying to use the same cert/key, but from the error we are getting it looks like the cert isn't being sent, since we are seeing the message "No required SSL certificate was sent" when we get the 400 error from nrf9160 error output

Hi,

Do you use socket offloading?

Do you get the same result if you use nrf_socket() and nrf_send() from nRF Socket Interface API?

[quote user=""]We have provisioned our device and verified the key,cert with a python script and that is able to hit our endpoint OK. However, when we try to do the same thing from the nrf9160 we are getting a `400 bad request No requried SSL certificate was sent` error[/quote]

Can you provide some details about "hit our endpoint OK"? What exactly did you try when you say: "when we try to do the same thing from the nrf9160 ..."?
