Sending email fails using django

I'm trying to send an email using django but keep getting authentication error

here's my settings

EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend"
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_USE_SSL = False
EMAIL_HOST = "smtppro.zoho.com"
DEFAULT_FROM_EMAIL = "myemail@mydomain.com"
EMAIL_FROM_USER = "myemail@mydomain.com""
SERVER_EMAIL = "myemail@mydomain.com"
EMAIL_HOST_PASSWORD = "*********"

And I use django's send email function

send_mail(
    subject=subject,
    message=text_message,
    from_email=settings.DEFAULT_FROM_EMAIL,
    recipient_list=recipients,
    html_message=html_message,
    fail_silently=False
)

I keep getting error authentication required

smtplib.SMTPSenderRefused: (530, b'5.5.1 Authentication Required.', 'myemail@mydomain.com')
