c# - AWS Request signature issue

Question

I am trying to use AWSSDK.S3's UploadAsync function to upload a file to my s3 bucket. However, I keep getting this error:

The request signature we calculated does not match the signature you provided. Check your key and signing method.

This is the code:

public static async Task UploadFileAsync(string bucketName)
    {
        try
        {
            Amazon.RegionEndpoint region = Amazon.RegionEndpoint.GetBySystemName("eu-central-1");
            var fileTransferUtility = new TransferUtility(my_access_key, my_secret_access_key, region);
            await fileTransferUtility.UploadAsync(filePath, bucketName);
            Console.WriteLine("test");
            Console.ReadKey();
        }
        catch(Exception e)
        {
            Console.WriteLine(e.Message);
        }
    }

I provide the upload function with my access keys which are correct, maybe is it because I have an IAM account? Is it necessary that the credentials are from the root user?
