Video Upload more than 100MB throwing 404 error

Question

I am trying to enable the functionality of video upload up to 190MB. I am using .Net core with Ocelot Gateway. I am able to successfully upload videos up to 190MB locally. But when I try to upload with Ocelot Gateway(on test environment), I am getting a 404 error. We have Cloudflare on the test environment and that is enabled for up to 200MB video upload.

I have applied following changes: In web.config of web project and gateway project

<system.web>
    <httpRuntime maxRequestLength="220200960" />
</system.web>

<requestLimits maxAllowedContentLength="220200960" />

On API Endpoint:

[RequestSizeLimit(220200960)]
[RequestFormLimits(MultipartBodyLengthLimit = 220200960)]

In web startup.cs

services.Configure<IISServerOptions>(options =>
{
  options.MaxRequestBodySize = int.MaxValue;
});
services.Configure<KestrelServerOptions>(options =>
{
  options.Limits.MaxRequestBodySize = int.MaxValue; 
});
services.Configure<FormOptions>(x =>
{
  x.ValueLengthLimit = int.MaxValue;
  x.MultipartBodyLengthLimit = int.MaxValue; 
  x.MultipartHeadersLengthLimit = int.MaxValue;
});

I am getting the following warning in Gateway:

Ocelot.Responder.Middleware.ResponderMiddleware[0] requestId: 0HMFB1RBKJ31C:00000001, previousRequestId: no previous request id, message: Error Code: UnmappableRequestError Message: Error when parsing incoming request, exception: System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown. at System.IO.MemoryStream.set_Capacity(Int32 value) at System.IO.MemoryStream.EnsureCapacity(Int32 value) at System.IO.MemoryStream.Write(Byte[] buffer, Int32 offset, Int32 count) at System.IO.MemoryStream.WriteAsync(ReadOnlyMemory`1 buffer, CancellationToken cancellationToken) --- End of stack trace from previous location where exception was thrown --- at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpRequestStream.CopyToAsyncInternal(Stream destination, CancellationToken cancellationToken) at Ocelot.Request.Mapper.RequestMapper.ToByteArray(Stream stream) at Ocelot.Request.Mapper.RequestMapper.MapContent(HttpRequest request) at Ocelot.Request.Mapper.RequestMapper.Map(HttpRequest request, DownstreamRoute downstreamRoute) errors found in ResponderMiddleware. Setting error response for request path:/v1/File/CreateFile, request method: POST

Nothing above helped me. Any help would be appreciated. Thank you in advance.

Looking at your stack trace, it mentions as out of memory exception, which could point towards an issue copying such a large file into memory (if your server has low free memory). Have you verified your server has > 200 MB of free memory at the time of upload?

I also found this post, which sounds like a somewhat similar issue with Ocelot - https://github.com/ThreeMammals/Ocelot/issues/884

Could try setting MaxRequestBodySize to null to see what happens? Although they were not receiving 'out of memory' exception, so could be unrelated.
