Could not locate PropertySource: I/O error on GET request for "http://localhost:8761/config/diviso/dev/master": Connection refused: connect; nested exception is java.net.ConnectException: Connection refused

This warning message means that your application could not connect to its spring cloud config server: JHipster Registry.

In dev profile, this is just a warning that you can ignore as your application can run with local application properties in sc/main/resources/config.

In prod profile, this would be an error and your application would not start. The registry must be started before your app because this is where your app gets its application properties from and registers itself as an Eureka client.

So in dev, you can ignore this warning or if it annoys you, you can start a registry.

If your app is a monolith application and not a microservice application, you can opt out the discovery client question, it'll be simpler to deploy if you don't need horizontal scaling.

The same issue happened with me, although I have already generated and modified my project before.

In case you are using MySql, go to phpMyAdmin page and type in your credentials. Worked for me.
