@joshy-mathew_7277 what type of package is this? HTTP is not a great protocol for pushing really large files like that, and things like IIS and Middleware breakdown with huge requests. ProGet doesn't have any limits per se, but the 503 error means that something between ProGet and your browser is killing the request. It's usually IIS. Most of the client tools (NuGet, etc.) do not support "chunked" file uploads (Docker does), which is why we recommend using drop folder for these large files.
