nrf9160 nRF cloud doesn't pair, stuck at CLOUD_EVT_PAIR_REQUEST

[samo4]

Hello,

I have a Thingy91 which was previously successfuly paired to nrf cloud. I deleted the device from nrf cloud and provisioned new certificates from nrf cloud (and uploaded to device). Now the device won't pair.. no error. See part of the log below.

[0m<dbg> nrf_cloud.api_event_handler: NRF_CLOUD_EVT_USER_ASSOCIATION_REQUEST

[0m<inf> asset_tracker: CLOUD_EVT_PAIR_REQUEST

[0m<inf> asset_tracker: Add device to cloud account.

[0m<inf> asset_tracker: Waiting for cloud association...

[0m<dbg> nrf_cloud_transport.nct_mqtt_evt_handler: MQTT_EVT_PUBACK: id = 1 result = 0

I also tried provisioning certificates with my custom prefix (and changing the NRF_CLOUD_CLIENT_ID_PREFIX), but the result is the same.

I'm currently using LTE-M, but I believe the original pairing was done with NbIOT. That being said.. I'm wondering how is NRFCloud able to support NBIOT (UDP?).

I’m not quite sure what 4294967293 and 4294967292 are, but given the type:

10 – Nordic identity root CA. Root CA for Nordic identity server.

11 – Nordic base public key. Used for ownership key provisioning message signature verification.

one might assume that they are necessary and thus non-erasable.

I have them on my DK with mfw 1.3.0 as well, which I successfully can connect to the nRF Cloud with.

Could you try to create a new certificate and connect to the nRF Cloud one more time now?

Thanks and regards,

Markus

ok, I got new certificate from nrfcloud (with prefix nrf-), I uploaded certificates to modem and uploaded assset tracker to Thingy.

When first booting, this is what I got:

asset_tracker: CLOUD_EVT_DISCONNECTED: 
asset_tracker: Disconnected by the cloud.
asset_tracker: This can occur during initial nRF Cloud provisioning.
asset_tracker: LTE link disconnect
asset_tracker: RRC mode: Idle
asset_tracker: Shutdown modem

Then a reboot occured, and we have the same situation as before:

asset_tracker: CLOUD_EVT_PAIR_REQUEST
asset_tracker: Add device to cloud account.
asset_tracker: Waiting for cloud association...
