Full traceback would help figure out what's missing here. There's no reason to have this with the code you've shown. – Linovia
I'm voting to close this question as off-topic because it is about third party web services that aren't mentioned. – Linovia
plz point out which third party api is calling ? – Ashok Kumar
The traceback is hardly human readable but you can see a couple of "xmlrpc/client.py" which means you're calling a 3rd party XMLRPC server. – Linovia
I'm New in Django, i don't know how it is calling. when i call the registration api on post method then all data was save except password and after user = User.objects.create( username=email.lower(), email=email.lower(), role_id=1, **validated_data) this script nothing returns in "user" – Ashok Kumar

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.

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
