cloud_connect failed: -111 error

[Laurin Rossmeier]

Hello,

I'm trying to set up my nrf9160 Dev Kit and I'm having problems connecting it to the nrfCloud.

Since I'm using it in Austria, I'm using a different sim card on LTE NB which I got working using some AT- Commands. 

The only problem is, that as soon the LTE connenction is established it throws the cloud_connect failed: -111  error and reboots.

I'm using the latest asset tracker and modem firmware and the same build runs fine on a different nrf9160 DK board. The sim card also works and has not run out of data.

The board I'm using may have been linked to a different nrfCloud account before but im not sure if that could cause the issue I'm getting.

I've tried some different builds and a  different board contoller firmware but the error remained.

I would appreciate if somebody could help me with this situation!

here is my LTE link monitor log:

Thanks in advance!

Hi, a possible reason for the -111 error is missing certificates. To check if they are still saved on the modem, add the following line to the prj.conf file in the asset tracker example and build / flash it again.

CONFIG_AT_CMD_RESPONSE_MAX_LEN=2560

Then open the nRF Connect LTE Link Monitor and do "AT%CMNG=1". If you have the correct certificates, the output should look something like this.

Best regards,

Heidi

Hello Heidi, Thanks for the quick response!

I've tried your suggestion and I just get a "ok" response on "AT%CMNG=1".

How can i install the certificates? shouldn't this work autmatically? why did it work on the other board?

Thank you! 

[Heidi-Irene Harvey Sollie]

Hi, you can recover your certificates by doing the steps described in the verified answer in this post, see image below.

It should work automatically, but the certificates can be overwritten or cleared from the modem for a number of reasons.

[Laurin Rossmeier]

So I fixed it now!

For anyone else with missing certificates:

this would work if you had previously connected your board to the nrfcloud.

If this isn't the case you can write a private ticket to the techsupport providing them the imei of your board and they will send you a new set of working certificates.

Thanks, Laurin
