RE: nRF7002-DK occurs SECURE FAULT when running https-client example

Update: I suspect it will work on your end if you disable IPV6 support in prj.conf. As of yet Im' not sure why this is the case but it fixed the hardfault on my end.

I am using NCS version 2.7.0.
I included the certificate (it was there when i first came to this example)
I forgot to tell you, the function "err = conn_mgr_all_if_connect(true);" always lead to FATAL ERROR: HardFault so I comment all these lines and then the SECURE FAULT happens

Here is my prj.conf:

CONFIG_PM=n

CONFIG_MAIN_STACK_SIZE=10240

CONFIG_MBEDTLS_CFG_FILE="mcuboot-mbedtls-cfg.h"

CONFIG_BOOT_SWAP_SAVE_ENCTLV=n

CONFIG_BOOT_ENCRYPT_IMAGE=n

CONFIG_BOOT_UPGRADE_ONLY=n

CONFIG_BOOT_BOOTSTRAP=n

### MCUboot has its own copy in tree.

# CONFIG_TINYCRYPT is not set

# CONFIG_TINYCRYPT_ECC_DSA is not set

Which version of NCS are you using and what is your build target?

Did you include the certificate to the server?

Could you please upload your prj.conf
