9160 unable to connect to nrf Cloud.

I am having a similar issue. My nRF9161 DK connects successfully to LTE, but fails to connect to nRF Cloud with a similar error message (attached screenshots).

nrf_cloud_integration: NRF_CLOUD_EVT_TRANSPORT_CONNECT_ERROR: -3

I was also having the issue of not being able to add the device to nRF Cloud. I followed one of the threads in the forum that suggested to use an older version of the Asset_Tracker_v2 NB-IoT application (nrf9160dk_asset_tracker_v2_nbiot_legacy_pco_2023-06-01_0677b099.hex). It did work and provisioned my device successfully, I could then see it in nRF Cloud. However I couldn't do much with it, because I don't have the whole project, only the .hex file, so I tried going back to the "Asset_Tracker_v2" from the samples.

I know the device is now provisioned and linked to my nRF Cloud, I know it connects to LTE, but fails to connect to nRF Cloud with this code. Hopefully someone can shine some light into the matter because I already spent a few days on this and I am making no progress. Thanks!

SOLVED:

I remove all certificates tag 16842753 from n9160 using commands:

AT%CMNG=3,16842753,0

AT%CMNG=3,16842753,1

AT%CMNG=3,16842753,2

AT%CMNG=3,16842753,3

AT%CMNG=3,16842753,4

And after that I loaded the certificate one more time, and now is working.

Yes, the same.

[quote userid="77062" url="~/f/nordic-q-a/104738/9160-unable-to-connect-to-nrf-cloud/450853"] Also, did you use the correct security tag when provisioning the credentials for nRF Cloud:16842753? [/quote]

yes

Hello
I'm using nrf 2.4.2
modem firmware 1.3.5

assert_trakker_v2 app is taken directly from nrf folders.

About new certificates: i generate them using https://nrfcloud.com/#/provision-devices later download and upgrade certificate using "lte link monitor"

Hello,

From our nRF Connect SDK documentation, the nRF Cloud connect result is used as return value for nrf_cloud_connect() and to describe NRF_CLOUD_EVT_TRANSPORT_CONNECT_ERROR event. This is also found under nrf/include/net/nrf_cloud.h.

From here we can see that this error means:

/** Other cert issue */

NRF_CLOUD_CONNECT_RES_ERR_CERT_MISC = -9,

Have you reprovisioned your newly generated certificates? What version of nRF Connect SDK and modem FW are you running?

Kind regards,
Øyvind
