Database connection refused

Completed

Hi.

I'm trying add db connection (postgres) in Rubymine (Mac OS X), but all time I get error 'Connection refused' after 1 minute waiting. I can connect to db from psql and from my ruby app, but rubymine (and datagrip) error all time. How can i fix it?

 

java.net.ConnectException: Connection refused (Connection refused).
java.lang.RuntimeException: java.rmi.ConnectException: Connection refused to host: localhost; nested exception is:
java.net.ConnectException: Connection refused (Connection refused)

 

UPD

I have same problem with datagrip.

Reinstall doesn't help
