ROR in which file is configured on the host?

With hosting was downloaded projects written in Rubu on Rails. Run in LAN, I get an error 500. In the logs the error 501 and you can see that the appeal goes through name operating address to an external host. In what file to replace to localhost:3000? Or how to replace the starter address to the default localhost:3000 on
