Before investigating this further, have you tested this out with the newest version of NCS master? The changes from https://github.com/NordicPlayground/fw-nrfconnect-nrf/pull/1982 are merged into the master.

If you're not able to make it work with master or if you have to stick with e.g. NCS v1.2.0, I'll take a closer look at your problem.

This case may be useful: https://devzone.nordicsemi.com/f/nordic-q-a/58664/nrf9160-fota-over-https

Best regards,

Thanks Simon, check my latest comment for current status. I have not had the opportunity to troubleshoot much further, but if I do I will post an update.

After pulling in some changes from https://github.com/NordicPlayground/fw-nrfconnect-nrf/pull/1986/files I was able to build the sample app successfully, but have received the following error.

Still working through to see what happened, but my guess is that the TLS credentials were not setup correctly.

I have made a very small amount of progress. Realized that the job document was not parsing the https for the aws_fota example, which is why I was able to still successfully update the app via AWS IoT Jobs. That discovery led me to this https://github.com/NordicPlayground/fw-nrfconnect-nrf/pull/1986/files - Which I started working through a bit of last night.

Just trying to piece it together now based upon some of what sigvart is already trying to accomplish.

Ultimate goal is to perform an aws_fota sample update via https.

I was able to confirm through server logs that even though the job document is set to https it is downloading over http. So it looks like I still have the issue at hand.

Just trying to understand how to set it to download over https based upon that latest merge.

Well, I hope it was not as easy as I think it was...

I just set the job document to https and submitted the job via the AWS console. The sample app grabbed the update and installed it, reflecting my updates.

I am just trying to check logs now to see if it actually downloaded over https....

I did this based upon the comment in the merge previously mentioned, excerpt is:

"I can probably add the protocol parsing into this PR for aws_fota library then it's only enabled if the user has specified in the job document that he wants to use https"
