Name resolving of a subdomain

Hi Charlie

My problem has indeed been solved. I had overlooked that both domain name and subdomain name were preceded by HTTP:/. This apparently results in the IP address of the main domain being returned during resolving in both cases. The function getaddrinfo() did not return any error.

Thank you for your help
Bert

Hi Bert,

[quote user="Bert Baselmans"]Unfortunately I am unable to generate the executable serial_LTE_modem due to configuration errors related to HTTP_CLIENT and MQTT. So I am unable to run the test using serial_LTE_modem. [/quote]

Please can generate another ticket and provide your configuration and logs for analysis. The precompiled SLM application firmware is available on nRF9160 DK - Downloads - nordicsemi.com.

I guess you mean your problem is solved. Correct? Let me know if you need more help.

Best regards,

Charlie

I hope this helps

Hi Bert,

Did you see any difference when you ping the two domains on PC terminal and Testing scenarios — nRF Connect SDK 2.0.2 documentation (nordicsemi.com) AT#XPING command?

I am interested to know the comparison result.

Best regards,

Charlie
