Troubleshooting Python api request error message "Remote end closed connection without response"

Question

Am trying to connect an API in my organization, but am always receiving the below error message. But being able to connect other similar API/reports using the same below script. Am able to get results when running the API URL in a web browser. So there is no authentication issues.

I believe the server closed before sending any response.

Kindly help me to resolve this.

import pandas as pd

         'authorization' : 'xyz'
         'cache-control': "no-cache"
         'postman-token: 'xyz'
}
