```invalid client``` error on auth/token with grant_type=password (production)

[krishnanpandya007]

I have my django apk. locally and also a copy on hosting server, however both uses same database, when i start my django server locally and try to send authentication request from frontend to backend, it works fine, but in production version it always shoes invalid client error with grant_type=password

Can you suggest where this erorr arises from actually,

thanks.
