I got this information when I tried to serve the Laravel project I hosted on railway.
Application failed to respond
This error appears to be caused by the application.
If this is your project, check out your deploy logs to see what went wrong. Refer to our docs on Fixing Common Errors for help, or reach out over our Help Station.
If you are a visitor, please contact the application owner or try again later.
I have gone to docs on Fixing Common Errors and I don't understand what to do about it.
No idea of where to include the host and port talked about.
I'm so confused.
I need an urgent response, please

when you run app locally by default it probably runs on port 8080, you can change thatm, or you can go to 'Settings' and on place where you generated your public domain you can add custom port and make it 8080
