Unable to upload attachments

Hi Team,

I am unable to upload attachments using an android client. Its throwing http 405 error code while calling uploadtoCdn function.

 org.whispersystems.signalservice.api.push.exceptions.NonSuccessfulResponseCodeException: Response: Response{protocol=h2, code=405, message=, url=https://cdn.xxxx.com/attachments/}

My CDN setup looks good but i suspect that CND doesn't expose any "attachment" endpoint instead it allows POST calls to its ROOT url only. Do I need to make any configuration changes to my CDN or Signal server to make it work?

Thank you.

if you cdn is CloudFront, AWS told me to operate on CF's root folder, that means you have to change upload path of attachments to "", and at the server side change objectName of attachments to prefix "attachments/" like profiles does.
