The cURL request was retried 3 times and did not succeed

[tyronemc2]

I am getting the below error when trying to send emails GuzzleHttp\Exception\RequestException cURL error 0: The cURL request was retried 3 times and did not succeed. The most likely reason for the failure is that cURL was unable to rewind the body of the request and subsequent retries resulted in the same error. Turn on the debug option to see what went wrong. See https://bugs.php.net/bug.php?id=47204 for more information. (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://graph.microsoft.com/v1.0/users/hello@example.com/sendmail

The HTTP response for the 3 retries. HTTP Error 411. The request must be chunked or have a content length.

Length Required HTTP Error 411. The request must be chunked or have a content length.
