OpenAPIScripMaster.json Download Failing After Latest Update (HTTP 200, Incomplete Response)

    Hi Team,

    We are facing a critical issue with the latest OpenAPIScripMaster.json endpoint:

    https://margincalculator.angelbroking.com/OpenAPI_File/files/OpenAPIScripMaster.json

    This endpoint was working perfectly until yesterday. After today's Script Master update, every download attempt fails.

    The server responds with HTTP 200 OK and advertises a Content-Length of 36,952,921 bytes, but the connection is terminated before the complete file is delivered.

    We have reproduced the same issue using:

    Python (requests)
    Python streaming download
    curl (HTTP/1.1 & HTTP/2)
    Google Chrome
    IPv4 & IPv6

    Errors observed include:

    IncompleteRead
    ChunkedEncodingError
    curl: HTTP/2 stream was not closed cleanly
    curl: end of response with bytes missing

    To rule out local issues, we also verified our internet connection by downloading large files from other HTTPS servers successfully at normal speed.

    No changes have been made to our code or infrastructure. Yesterday's Script Master (~19 MB) downloaded successfully, but today's updated Script Master (~37 MB) consistently fails before completion.

    This is currently blocking our production trading system, as the Script Master is required before initialization.

    Could the SmartAPI team please check whether there is any issue with the latest Script Master file or the server/CDN serving this endpoint? Is anyone else experiencing the same issue today?

    Thank you.

    Multiple people are facing these issues and the admins here on this forum either do not exist or are completely unequipped to deal with anything other than giving vague useless replies. I have sent a detailed mail to support@angelone.in and escalation@angelone.in. If there is no satisfactory resolution, I'm planning to escalate directly to the CEO, Mr Ambarish Kenghe (ceoescalation@angelone.in) and post it all over social media like X/Twitter, tagging AngelOne's X handle.

    I suggest everybody facing issues use these channels as well to voice their issues since the administrators of this form have proved themselves completely incompetent.
