Been having the same issue, have updated the certificates and updated the modem and application firmware, is there yet any solution to this?

I made the certificate (also check/update IMEI) and firmware update. Still the same issues. Any ideas ?

Ok, there has been some updates to the certificate recovery procedure, please run through the updated guide step-by-step.

verified, it matches. issue still happen (restarted multiple times)

Ok, then make sure the kits IMEI number, the clientId above(used for delete) and the clientId inside the downloaded certificate JSON file all matches. Both clientId should be nrf-<IMEI>. If all that matches then make sure you are running lastes modem FW and latest asset tracker application.

BTW: its also expected to get a POLLHUP the first time a kit connects after it has been deleted. The application should then ensure it reboots and then it should work the second time it tries to connect!

done removing device using curl. problem remains ...

RE: nrf9160 Socket error: POLLHUP

Joakim — Mon, 07 Oct 2019 08:56:19 GMT

yes you can. clientId is nrf-<IMEI> and your IMEI should be found on a label on your kit. From the logs you posted earlier, it seems to be: nrf-352656100222853.

HWID format also looks correct.

BTW, regarding the HWID: should I enter in format of XX:XX:XX:XX:XX:XX ? if not then in which format?

I can not since the device has been already removed from the cloud, and can not be added.

so I can not fill in : <clientId>

RE: nrf9160 Socket error: POLLHUP

Joakim — Sat, 05 Oct 2019 22:28:36 GMT

Ok, try to make sure the device is completely removed by using the curl command from the guide to delete the device.

did all the steps described:

updated certificates successfully

deleted device from cloud

tried to register device to cloud

device still reset for the same reason

PCA10090, HW version 0.8.5

please advice

*note this board worked fine until ~ 8 days ago.

thank you

You should all try to run the following guide (again if already done): https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/nrf-cloud-certificate-update

If you are updating the certificates on a kit without PIN, its important to remember that after running through the above steps the kit should be added to nRF Cloud using the IMEI and PIN/HWID method, not the legacy button and switch method.

exactly my issue!

I have even done the following steps:

1. removed the device from cloud

2. completely deleted my account and opened a new one

3. replaced both SIM card and board

4. updated modem FW

I too have an old devkit without a PIN (but new HW version 0.8.5)

it also worked for me very well until last week

I suspect it's due to a new update on NRF cloud ...

I have a same problem. I cannot add the nRF9160-DK to nRF cloud because the device will not go to the pairing state(getting Socket error: POLLHUP). I have an old devkit without a PIN. I have updated the modem SW and also certificates. Device was working earlier and suddenly stop working so i removed the device from the nRF cloud. Now try to add it back.
