sorry for bother but actually i changed 1 import and the error is changed in : Is the server running on that host and accepting TCP/IP connections?

You're attempting to connect to something through localhost, that's why it's failing On Railway, whatever that is should be hosted as a second service and connected through private networking Looks like it's your db that is failing to connect what sort of db is it?
