https_client connection results in error 22 on nRF7002dk

Hardware CI

Hi,

I took a HTTPS Client Sample application from nRF SDK v2.6.2 and I cannot make it work.

What I figured out already is that SSL certificate for 'example.com' has changed from Digi Cert Global G2 to DigiCert Global G3. However It still doesn't connect properly.

The only changes that I have done is swapping the SSL certifitacte and adding WIFI credfentials. This is my prj.conf:

CONFIG_WIFI_CREDENTIALS_STATIC=y
CONFIG_WIFI_CREDENTIALS_STATIC_SSID="abc"
CONFIG_WIFI_CREDENTIALS_STATIC_PASSWORD="xyz"
CONFIG_DNS_RESOLVER=y

The result is as follows:

I also tried it on the latest nRF SDK 2.9.0 and it doesn't connect either.
Please provide a config that works with this sample on nRF7000dk.

I am looking forward for your support!

    Net credendials (ssid+password) are fine. You can tell by the successful DNS resolve of the hostname.
    I am providing detailed net logs as requested:

    I also provide zip with modified examples from both SDK versions:
    6521.https_client.zip
    I included up-to-date pem files:

    • DigiCertGlobalG3.pem
    • fullchain.pem (DigiCertGlobalG3 + DigiCert Global G3 TLS ECC SHA384 2020 CA1).

    Both pem files you can positively verify using python script (certs/test.py). 

    For 'https_client_2_6_2' I use NRF SDK 2.6.2 and toolchain 2.6.2.
    For 'https_client_2_9_0' I use NRF SDK 2.9.0 and toolchain 2.9.0.

    It fails in a somewhat similar way for me as well. 

    I've forwarded this to the relevant R&D team, and will update you when I hear from them.

    Thank you Elfving,
    This is a blocker for me at the moment, so I’d be grateful for any guidance.

  • 0 in reply to Hardware CI

    Understood.

    I'm a bit unclear about whether or not this solves it all for me, but could you try this fix? I've heard claims that this should be the problem.

    Regards,

    Elfving

    Yes, I've already replaced the certificate with the proper one (DigiCertGlobalG3.pem)
    I included this information in my original post.

    "What I figured out already is that SSL certificate for 'example.com' has changed from Digi Cert Global G2 to DigiCert Global G3. However It still doesn't connect properly."
