Getting Connection Reset error while acquring azure access token

Question

I am using UsernamePasswordFlow for acquiring accessToken. I followed below example for writing code for my application.

https://github.com/AzureAD/microsoft-authentication-library-for-java/blob/dev/src/samples/public-client/UsernamePasswordFlow.java

UserNamePasswordParameters parameters =

                    UserNamePasswordParameters
                            .builder(scope, username, password.toCharArray())
                            .build();
            // Try to acquire a token via username/password. If successful, you should see
            // the token and account information printed out to console
            result = pca.acquireToken(parameters).join();

The PublicClientApplication.acquireToken() method works but every now and then i see below error:
