ROR in which file is the host configured?

Question

Ruby on Rails

A project written in Rubu on Rails was downloaded from the hosting. Running in the locale gave an error 500. In the logs, an error 501 and it is also visible there that the call goes through the name of a functioning address on an external host. In which file should I replace it with localhost:3000? Or how to replace the default start address localhost:3000 with saitpupkina.com?

Answer 1

add
127.0.0.1 saitpupkina.com to hosts
and call saitpupkina.com:3000
ps: the bind is not bound to a domain name
