RE: 9160DK: http_client sample connect() failed with error 60

Hi Heidi

I tried the MQTT_Simple sample and made some configurations in prj.conf adapted for NB-Iot network, The MQTT_Simple sample always runs well and no need extra modifications in the code.

About the HTTPS_CLIENT sample, I guess its because I 'm in China-mainland and have no access to google.com without VPN.

So I tried to connect www.bing.com with its cerification, it works well finally. like :

*** Booting Zephyr OS build v2.1.99-ncs1  ***
HTTPS client sample started
Provisioning certificateWaiting for network.. OK
Connecting to bing.com
Sent 62 bytes
Received 810 bytes
> HTTP/1.1 302 Found
Finished, closing socket.

So I think I solved the problem.

Thanks for your help.

Hi!

As Håkon states in the ticket you linked to:

The behavior you see is highly likely inherited from the network that you are connecting to.

Have you tested if TCP works at all in your current network?

Did you try mqtt_simple, where you set the IP manually in prj.conf? mqtt.eclipse.org currently resolves to 137.135.83.217, so that would be:

CONFIG_MQTT_BROKER_HOSTNAME="137.135.83.217"

If that fails, try an UDP based sample, like this one (change define NTP_HOST to 129.240.2.6):

Did you do this?

Best regards,
