Hey, Sigurd thank you for your response. I have it resolved now, a couple of steps:

1) I converted my certs to DER and added them manually, CONFIG_MBEDTLS_PEM_CERTIFICATE_FORMAT does not seem to work, at-least with WPA enabled.

2) I rolled back to 2.5.1 from 2.6.1 it almost seems like 2.6.1 requires the _ns built with CONFIG_TLS_CREDENTIALS_BACKEND_PROTECTED_STORAGE=y for TLS certs to be retrieved properly via SEC tags.

[quote user="mahabib"]I am getting the same error setting my TLS certs this way, as well. [/quote]

Let us take this one step at a time, so we can figure out where things goes wrong.

Did the HTTPS Client sample work out of the box?
Which changes did you make to the sample when it stopped working?

Unfortunately I am getting the same error setting my TLS certs this way, as well.

I am using the AWS IoT Connect helper function/library with CONFIG_MQTT_HELPER_PROVISION_CERTIFICATES=n (setting them my self)

Hi,

See our HTTPS Client sample for how to do TLS with the nRF7002.
Observe also how it is converting its .pem to .inc in CMakeLists.txt.
