Handle 504 Timeout for Download API

[ducttri]

Vercel put a limit on Download API at the 60s for the Hobby plan. It is currently set to 60s but there could be a problem if there is more data. Some ideas for improvement could be to check for status codes for 504 and split files into multiple smaller requests to download safely.
