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,

Achim Kraus, thank you for providing your merged.hex file. I have verified that it is working as intended, without errors.

chcortes559123, could you try testing with provided merged.hex file to verify that it is working on your end as well. Afterwards, please try updating your modem firmware and provide results.

Best regards,
Dejan

In case this is still relevant, I was experiencing the same issue as chcortes559123  with SDK v2.4.2 and nRF9160DK. I found that swapping the certificate for the one provided in this answer resolved the issue and I was able to get the expected result with the new cert:

*** Booting Zephyr OS build v3.3.99-ncs1-2 ***
HTTPS client sample started
Certificate mismatch
Provisioning certificate
Waiting for network.. PDP context 0 activated
PDP context 0 error, PDN type IPv4 only allowed
OK
