if you have used email as username field, (i.e. in custom User model class: USERNAME_FIELD = 'email') and using dj_rest_auth and allauth for auth,

then follow along.

if you are testing auth and does not just want email to be sent now, then add the below in settings.py -

non email verification

ACCOUNT_USER_MODEL_USERNAME_FIELD = None
ACCOUNT_EMAIL_REQUIRED = True
ACCOUNT_USERNAME_REQUIRED = False
ACCOUNT_AUTHENTICATION_METHOD = "email"
ACCOUNT_EMAIL_VERIFICATION = "none"

for email verification:

ACCOUNT_AUTHENTICATION_METHOD = "email"
ACCOUNT_EMAIL_REQUIRED = True
ACCOUNT_EMAIL_VERIFICATION = "mandatory"
ACCOUNT_CONFIRM_EMAIL_ON_GET = True
ACCOUNT_EMAIL_CONFIRMATION_EXPIRE_DAYS = 1
ACCOUNT_USER_MODEL_USERNAME_FIELD = None
ACCOUNT_USERNAME_REQUIRED = False

if you are using username as username-filed, then add the below in settings.py as iamsaiful has noted.

ACCOUNT_EMAIL_VERIFICATION = 'none'
ACCOUNT_AUTHENTICATION_METHOD = 'username'
ACCOUNT_EMAIL_REQUIRED = False

I was getting the same error and it may be due to email verification. I add following code in my setting.py file and now authentication working perfectly


ACCOUNT_EMAIL_VERIFICATION = 'none'

ACCOUNT_AUTHENTICATION_METHOD = 'username'

ACCOUNT_EMAIL_REQUIRED = False

You perform a call to a remote server that you can't reach / isn't configured / isn't running.

It's not an issue with Django or DRF.
