SharePoint 2016 500 (Internal Server Error) When uploading

Hello Everyone, i am facing an issue with Sp16 when i upload many documents using rest API. when i upload many documents each one is 20mb i am receiving error 500 Internal server error.

any idea about this error and how to solve it?

i tried this https://www.vioreliftode.com/index.php/how-to-make-sharepoint-2016-not-fail-long-running-uploads-large-files/ but it didn't work for me. any other suggesstions?

my post request is below

public async Task<bool> Save(string requestUri, HttpContent content)
{
var credential = new System.Net.NetworkCredential(
username,
password,
domain);
using (var handler = new HttpClientHandler() { Credentials = credential, UseProxy = false })
{
using (var client = new HttpClient(handler))
{
client.DefaultRequestHeaders.Accept.Clear();
var mediaType = new MediaTypeWithQualityHeaderValue("application/json");
mediaType.Parameters.Add(new NameValueHeaderValue("odata", "nometadata"));
client.DefaultRequestHeaders.Accept.Add(mediaType);
client.DefaultRequestHeaders.Add("X-RequestDigest", await this.GetRequestDigest());
client.DefaultRequestHeaders.Add("binaryStringRequestBody", "true");
string postUrl = this.siteUrl.EndsWith("/") ? $"{this.siteUrl}{requestUri}" : $"{this.siteUrl}/{requestUri}";
this.logger.LogDebug("Executing SharePointService.Save: PostUrl={0}.", postUrl);
HttpResponseMessage response = await client.PostAsync(postUrl, content);
response.EnsureSuccessStatusCode();
this.logger.LogDebug("Executed SharePointService.Save: PostUrl={0}", postUrl);
return true;
}
}
}

Try this method for uploading large file.

Sample:

MemoryStream destStream;
using (System.IO.FileStream fInfo = new FileStream(fileInfo.FullName, FileMode.Open))
{
byte[] buffer = new byte[16 * 1024];
byte[] byteArr;
using (MemoryStream ms = new MemoryStream())
{
int read;
while ((read = fInfo.Read(buffer, 0, buffer.Length)) > 0)
{
ms.Write(buffer, 0, read);
}
byteArr = ms.ToArray();
}
destStream = new MemoryStream(byteArr);
Microsoft.SharePoint.Client.File.SaveBinaryDirect(
context,
serverRelativeURL + directory + fileInfo.Name,
destStream,
true);
context.ExecuteQuery();
results = "File Uploaded";
return true;
}

        }
        byteArr = ms.ToArray();
    }

    destStream = new MemoryStream(byteArr);

    Microsoft.SharePoint.Client.File.SaveBinaryDirect(
        context,
        serverRelativeURL + directory + fileInfo.Name,
        destStream,
        true);

    context.ExecuteQuery();
    results = "File Uploaded";
    return true;
}
