NRF9160 https_client does not connect to example.com

[chcortes559123]

1. am currently using the nrf9161_dk. and have not modified the modem FW in anyway. 

2. I am using the vscode extension provided by nordic to build/run this sample

        a, i am using version v2.4.1 for the SDK

3. this is my build config.  with this configuration  get the err 111 which when i look it up means   #define ECONNREFUSED 111   /* Connection refused */

this is the output:

*** Booting Zephyr OS build v3.3.99-ncs1-2 ***
HTTPS client sample started
Certificate mismatch
Provisioning certificate
Waiting for network.. PDP context 0 activated
OK
Looking up example.com
Resolved 93.184.216.34 (AF_INET)
Connecting to example.com:443
connect() failed, err: 111
PDP context 0 network detached

So then i tried adding mbed tools as well: 

build config with mbed tool: 

and i get this errno 22 #define  EINVAL 22   /* Invalid argument */ 

So then i has a thingy91 and decided to test that dev kit out, i uploaded that modem with mfw_nrf9160_1.3.5.zip  and i am running the exact same configurations and i am getting the same errors. 

does anyone have any ideas of what might be happening here and why the sample is not working, any input is appreciated. 

thanks,

Hi,

Could you please test the same sample in NCS v2.6.0? Do you get the same errors?

Best regards,
Dejan

Dejans, did you check, if that works with NCS v2.6.0?

[Achim Kraus]

I checked it with a nRF9160-DK and a nRF9161-DK, NCS-2.6.0:

Works with both.

Hi,

chcortes559123 , I have tested https_client sample on nrf9161-dk in both NCS v2.4.1 and v2.6.0. I have observed the same errors as you when using nrf9161-dk in NCS v2.4.1 (errors 111 and 22). I got different errors in NCS v2.6.0. 
Achim Kraus , we have tested internally on another nrf9161-dk board and results were the same as you reported, without errors.
We would need some time to investigate further why we got different results. We will further look into this issue during next week.

Could you chcortes559123 and Achim Kraus provide information about the versions of your nrf9161-dk boards that you used for testing?

Best regards,
Dejan

[Achim Kraus]

nRF9160-DK: v1.1.0, NCS: 2.6.0, HW: B1A, MFW: 1.3.5

nRF9161-DK: v0.9.1, NCS: 2.6.0, HW: ADA, MFW: 2.0.0-77.beta

[chcortes559123]

[Achim Kraus]

Just if you like, should I upload the merge.hex?

[dejans]

Hi,

Achim Kraus Yes, you could upload your merged.hex file.

chcortes559123 , could you try to update your modem firmware to the latest version 2.0.1 which you can find on the product page?

Best regards,
Dejan
