Partial Request made for a Google Drive file does not return the expected content

Question

I am working on a download manager. I tried to download a content from Google Drive. I used AddRange to get the file partially but despite Range:60000000-61000000 returns the correct size, the Range:600000000-610000000 returns -1. It doesnt overflow the file size which is almost 1.3GB. I dont understand why this problem happens. How can I fix it?
