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

[Smile Jiang]

Hi Support Team

     I try to run the http_client sample based on ncs1.2.0,  and I use the following configs because only NB-Iot available in our location: 

     

CONFIG_BSD_LIBRARY=y
CONFIG_BSD_LIBRARY_SYS_INIT=n

CONFIG_NETWORKING=y
CONFIG_NET_SOCKETS=y
CONFIG_NET_NATIVE=n

CONFIG_HEAP_MEM_POOL_SIZE=4096
CONFIG_MAIN_STACK_SIZE=4096

CONFIG_MODEM_KEY_MGMT=y
CONFIG_LTE_LINK_CONTROL=y

CONFIG_LTE_NETWORK_MODE_NBIOT=y
CONFIG_LTE_LEGACY_PCO_MODE=y
CONFIG_LTE_PSM_REQ_RPTAU="00000110"
CONFIG_LTE_PSM_REQ_RAT="00000000"

     when start running the sample, the terminal prints as:

     

*** Booting Zephyr OS build v2.1.99-ncs1  ***
HTTPS client sample started
Provisioning certificate
Waiting for network.. OK
Connecting to google.com
connect() failed, err: 60

     I try to find solutions from devzone; and find this tickets: 

https://devzone.nordicsemi.com/f/nordic-q-a/58556/basic-http-get-example/237525#237525, according to the suggestions in the ticket, I try to use "216.58.208.174" replace "google.com" but it didn't work(  I think it's not the root cause for my case, for my getaddinfo() is always ok   ); I also tested the mqtt_simple demo, whether use the defalut code directly or add the configure 'CONFIG_MQTT_BROKER_HOSTNAME="137.135.83.217"', the sample can runs well...

     So I still have no idea to deal with the "connect error 60" of the http_client sample. Can you give some suggestions?

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.
