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,

hello, i updated the SDK to v2.6.0 and the toolchain is also at v2.6.0. now i am getting deprecation warnings like 'lte_lc_init_and_connect' is deprecated. i can still run the  example, another difference now is that if i only add the ipv4.conf i get the same 111 error, but if i add the mbed.conf file, i get the following errors C:/ncs/v2.6.0/nrf/ext/oberon/psa/core/library/check_crypto_config.h:106:2: error: #error "PSA_WANT_ALG_RSA_PKCS1V15_CRYPT defined, but not all prerequisites"
106 | #error "PSA_WANT_ALG_RSA_PKCS1V15_CRYPT defined, but not all prerequisites"
| ^~~~~
C:/ncs/v2.6.0/nrf/ext/oberon/psa/core/library/check_crypto_config.h:112:2: error: #error "PSA_WANT_ALG_RSA_PKCS1V15_SIGN defined, but not all prerequisites"
112 | #error "PSA_WANT_ALG_RSA_PKCS1V15_SIGN defined, but not all prerequisites"

so it seems that v2.6.0 does not work either
