Error getting when call aws api

http://nestapplication-env.eba-wwb3m3pd.us-east-1.elasticbeanstalk.com
I called this url from my android app using retrofit client, but i got the error below:-

E/Failed call: CLEARTEXT communication to nestapplication-env.eba-wwb3m3pd.us-east-1.elasticbeanstalk.com not permitted by network security policy
Why i get this error and how to resolve this.

Hello!

CLEARTEXT means you didn’t use any method of encryption to secure the connection to the API. In your case, you didn’t use https: https://nestapplication-env.eba-wwb3m3pd.us-east-1.elasticbeanstalk.com
