I am able to create ml model server using following command
mlflow models serve -m file:///C:/Users/SawarkarFamily/Desktop/mlflow-master/examples/sklearn_elasticnet_wine/mlruns/0/9aeb7ba16d7e4c20870b664e267524ea/artifacts/model -p 8000

In documentation it is given that send that for prediction using curl command as follows:
curl -X POST -H "Content-Type:application/json; format=pandas-split" --data '{"columns":["alcohol", "chlorides", "citric acid", "density", "fixed acidity", "free sulfur dioxide", "pH", "residual sugar", "sulphates", "total sulfur dioxide", "volatile acidity"],"data":[[12.8, 0.029, 0.48, 0.98, 6.2, 29, 3.33, 1.2, 0.39, 75, 0.66]]}' http://127.0.0.1:1234/invocations
I replaced port number with 8000, but getting error.

Kindly someone help me with this.
