Hi all,

currently i am trying to run an OTA update on Android 10. I used the updater sample app inside AOSP as a reference and extended it to stream update packages from a server.

When i initiate the streaming process using a HTTPS url, the UpdateEngine immediately returns prompting the message DOWNLOAD_TRANSFER_ERROR. When i want to stream the same package using a HTTP url, the UpdateEngine is downloading it without any issue.

Following the Google docu about OTA, it seems that HTTPS is supported by UpdateEngine: https://source.android.com/devices/tech/ota/ab#overview

But actutally there is not much what i can set except user-agent (used the default of updater sample) and authorization (not set as i dont have access restrictions)
