Getting Exception: The specified network name is no longer available. (0x80070040) when trying to read HttpRequest Body using ReadToEndAsync()

I have an API post web method that tries to get the request body out using StreamReader ReadToEndAsync(). The majority of the time it works fine, however for very random request I am getting the following exception:

The client has disconnected.

with inner exception

The specified network name is no longer available. (0x80070040).

[HttpPost]
[Route("api/Logger/Log")]
public async Task<IActionResult> Log()
{
    try
    {
        HttpHelper httpHelper = new HttpHelper();
        var requestBody = await httpHelper.GetRequestBody(Request);
        return Ok();
    }
    catch (Exception ex)
    {
        _logger.LogException(ex);
        return StatusCode(500);
    }
}

public async Task<string> GetRequestBody(HttpRequest request)
{
    using (var reader = new StreamReader(request.Body))
    {
        return await reader.ReadToEndAsync();
    }
}

What is the cause for this? Is the way that I am reading the request body not correct? How can I resolve this?
