Well, the solution was pretty stupid. I found out on nRF Cloud that I don't have remaining data left. It started working, when I bought a data.

The same error ocurrs also on Azure IoT Hub sample and when I try to fetch datetime from NTP server.

I managed to get your Zephyr OS build. It still doesn't work. I flash Thingy 91 by Segger J-Link EDU.

How do you program the Thingy91? Please check Program the nRF9160 SiP application.

If you program the image correctly, it would look like this

Here is a screenshot from nRF extension for VS code.

I deleted a previous build and made another one.

*** Booting Zephyr OS build 28a3fca7da5c ***

The first line of the log is still the same.

Your first line of the log is different from mine. Please make sure to flash with the new image.

I've just tested your project and it results the same. :(

Do you delete the build folder and build again?

Here is my test project devzone.nordicsemi.com/.../cellfund_5F00_less3_5F00_exer1_5F00_solution_5F00_google.7z for NCS v2.4.2.

Beware that this code/configuration is not fully tested or qualified and should be considered provided “as-is”. Please test it with your application and let me know if you find any issues.

Hello, thank you for your response. Unfortunately, an error is still the same. :(

Hi,

I set the server name and port as

#define SERVER_HOSTNAME "www.google.com"
#define SERVER_PORT "465"

and it can connect as this log:
