Hi Nordic,
Environment
nRF SDK 1.9.1
device - nRF1960
Server
The application and delta modem update files are stored on the AWS S3 bucket and served by the AWS cloudFront.
These files are accessed and downloading by basic authentication in the device. Uses HTTPS prototol (42 securiy tag). CA certificate provision has been writen to the modem.
Problem
I am facing this below problem during delta modem update using fota download. I am successfully able to download application fota update but not the delta modem update.
I am downloding application update first and after that delta modem update.
It was possible for me to download both the upates two months back but not now. In november 2022, CA certificates got renewed.
If I use new CA certificate to access and download the fota updates I get below error.
[09:09:41.130,500] <err> download_client: Unable to connect, errno 111
if i use old CA cerificate, I got below error.
