Hi everybody,

 

When I use the tool "root_certificate_downloader.exe" to download google certificate file, I got connection successful.

 

But when I use example "CERT_DOWNLOADER_OTA_HTTPS_DOWNLOAD_EXAMPLE1" to download the same certificate, I got connection error -12.

 

The certificate I used is GS Root R2 downloaded from https://pki.goog/

 

I set ROOT_CERT for this certificate when run the example.

 

Anyone has experience with this issue, please?
