                fin = true;
                var response = await client.PostAsync(uri, content);
                if (response.IsSuccessStatusCode)
                {
                    var result = await response.Content.ReadAsStringAsync();
                    try
                    {
                        var Items = JsonConvert.DeserializeObject<List<string>>(result);

After communicating with a friend After searching a lot, I found the cause of the problem is the server itself iis As it gives a default value for the maximum upload limit of 2 megabytes

Solve the problem if the server is on iis

IIS -> web. config :

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.web>
    <!-- ~ 2GB -->
    <httpRuntime maxRequestLength="2147483647" /> // kbytes
  </system.web>
  <system.webServer>
    <security>
      <requestFiltering>
        <!-- ~ 4GB -->
        <requestLimits maxAllowedContentLength="4294967295" /> // bytes
      </requestFiltering>
    </security>
  </system.webServer>
</configuration>
