Unable to use docker registry

[princesaini1996]

docker {
useApi true
registry 'http://IP:5000'
apiEmail 'xyz@gmail.com'
baseImage "openjdk:8-jdk-alpine"
maintainer "Prince"
}

error: java.net.ConnectException: Connection refused (Connection refused)
But registry is running on 5000 port.

Thanks,

I think the connection refused is actually a response from the Docker API, not the registry.
Will need more information to give a more accurate answer, like Gradle version and gradle output with stacktrace.

I have some more information.

I've got a registry setup using a username/password via NGINX. I get the same connection reset error, however, on NGINX I see the following log:

"POST /v1.11/build?t=group/application:1.1.0 HTTP/1.1" 401 195

Does the client properly use basic authentication?
