HTTP2 PROTOCOL Error on Production server RRS feed

  • Question

  • While using https with IIS we are intermittently getting ERR_HTTP2_PROTOCOL_ERROR on Dev tool in Production env.

    This works fine with http protocol (QA Env). We are using IIS 10.

    We are using React Framework 16.11.0 version and the fetch method fails.This happens in all the browser (edge, chrome etc)

    Sharing below the net log data.

    {"params":{"description":"Server reset stream.","net_error":"ERR_HTTP2_PROTOCOL_ERROR","stream_id":183},"phase":0,"source":{"id":2567,"start_time":"1619763469","type":1},"time":"1619779275","type":222},

    Please let me know if I need to share any other info.

  • Hi TahirHussain,
    The Visual C# forum discusses and asks questions about the C# programming language, IDE, libraries, samples, and tools.
    So I will move it to "where is the forum for" form and the case will be redirected to correct forum.
    Thank you for your understanding.
    Best Regards,
    Daniel Zhang

  • Oh, I hate generic error messages.

    Btw, the Edge browser you used to test can actually be Chromium based one, and a frequent scenario you see this error is Chrome is very unforgiving on Content-Length header mismatch against the actual data size transferred. If Firefox don't complain that this could be the problem.

    Using a debugging proxy such as Fiddler may give you more concrete error message.
