Failure connecting to example.com while running sample: https_client

Jacek Majda

After programming the sample to my nRF9160 DK, I opened the terminal emulator and I observed the following messages:

1. HTTPS client sample started

2. Provisioning certificate

3. Waiting for network..OK

4. Connecting to example.com

5. connect() failed, err 116

I am using the following:

1. nRFD9160 DK v0.8.2

2. Windows10 O.S. version:20H2, OS build:19042.631

3. nRF Connect v 3.7.0

4. nRF Connect SDK v 1.6.1

I attach the log file from the LTE Link Monitor below:

    Hello Markus,

    It appears that I already used modem firmware  1.3.0 when I was recording the last trace. However, to be dead sure, I did repeat the upgrade of the modem firmware this morning, using the mfw_nrf9160_1.3.0 zip file.

    I then run again the sample: AT_Client, successfully.  I noticed that it took about 25 seconds from the time when the modem was switched ON by the command: AT+CFUN=1, before the connection to the NB-IoT network was made, as confirmed by the response to the  AT+CEREG? command, in the form of: +CEREG; 0,1,"5209","099F990D",9

     Then I run the sample: Asset_Tracker and it worked OK. I was able to connect to the NB-IoT network and to the nrf Connect for Cloud.

    I then run the sample: sms and the sample: https_client and both attempts were unsuccessful. The same error messages as reported by my in the past, appeared again today.

    I attach the latest file created today in the process of capturing the modem trace, while running sample: https_client.  I made sure that I saw the error message: "connect() failed, err 116" on the LTE Link Monitor, before I clicked "Stop Capture" on the Trace Collector app.
