Error: SignatureDoesNotMatch when calling the GetSendQuota operation

[looeee]

I'm getting the following error:

An error occurred (SignatureDoesNotMatch) when calling the GetSendQuota operation: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.

I have created an IAM user using this doc then gave them full SES permissions by adding them to the AMAZONSESFullAccess group:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "ses:*"
            ],
            "Resource": "*"
        }
    ]
}

In my Django config I have set:

AWS_ACCESS_KEY_ID = "**************"
AWS_SECRET_ACCESS_KEY = "*****************************************************"
AWS_SES_REGION_NAME = 'eu-west-1'
AWS_SES_REGION_ENDPOINT = 'email.eu-west-1.amazonaws.com'

EMAIL_BACKEND = 'django_ses.SESBackend'

My server time is set to GMT, the same as eu-west-1

Now when I try to send an email using

send_mail("testing", "text body", "me@mysite.com",
          ["to@mysite.com"], fail_silently=False)

I get the above error. Both me@mysite.com and to@mysite.com are replaced by my AWS verified email addresses. Any ideas what might be causing the error?
