Ruby on Rails/Postres Task Error

Hi I'm looking for some quick help after one of our linux servers rebooted. Getting the following error now from our rails app. The app still works and runs ok it seems just this task is failing for some reason. Task: check_late_staff Message: could not connect to server: Connection refused Is the server running on host "[login to view URL]" and accepting TCP/IP connections on port 5432? Trace: /usr/local/rvm/gems/ruby-2.3.1/gems/activerecord-4.2.0/lib/active_record/connection_adapters/[login to view URL]:in `initialize' /usr/local/rvm/gems/ruby-2.3.1/gems/activerecord-4.2.0/lib/active_record/connection_adapters/[login to view URL]:in `new' /usr/local/rvm/gems/ruby-2.3.1/gems/activerecord-4.2.0/lib/active_record/connection_adapters/[login to view URL]:in `connect' has maybe 30 more lines
