Hello,
I am currently working with the Nordic nRF9160DK and am using the https_client example from the examples in the nRF Connect via VS Code (on Windows OS), and as far as I know it is the latest release (v2.7.0). I have already successfully established a connection with example.com and was able to send/receive data. However, I am having some issues when attempting to change the certificate. I am attempting to connect to dweet.io, and when running the demo, I receive an output which says "Certificate mismatch" and "err: 111" (see image below):
I have also received a different output before as well (shown below):
I made the following changes to the source code based on what seemed like it had needed changing and based on previous DevZone posts I have seen with similar issues. I linked the main issue that I followed here: changing certificate in https_client sample
I also referenced the following documentation:
https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/net/https_client/README.html
https://docs.nordicsemi.com/bundle/ncs-2.4.0/page/zephyr/connectivity/networking/api/http.html
Added the .pem file (filename dweet.io.pem) in the /cert directory, as well as added "...\n":
Updated the certificate definition in main.c:
Changed HTTPS_HOSTNAME in kconfig:
I also attempted to change the CMakeLists.txt file to include the dweet.io.pem:
I do not believe this to be an issue with the SIM card, since I am using the nanoSIM that was included with the 9160DK, and had no issues when connecting to example.com
Any help in resolving this issue would be greatly appreciated.
