Application Not working

It's my first time using railway, and I followed a video, but mine is not working, I followed the exact steps. In the deploy logs I see my messages for successfull connections to server and database (server connected and database connected). But when I access the genereated link, I get "Application failed to respond". What might be the cause of the problem?

// Use PORT provided in environment or default to 3000
const port = process.env.PORT || 3000;

// Listen on `port` and 0.0.0.0
app.listen(port, "0.0.0.0", function () {
  // ...
});

// Use PORT provided in environment or default to 3000
const port = process.env.PORT || 3000;

// Listen on `port` and 0.0.0.0
app.listen(port, "0.0.0.0", function () {
  // ...
});

This is provided as the solution for this problem.. But my question is, if I update my code with app.listen(port, "0.0.0.0" ... ) shouldn't it automatically start on the port variable defined earlier?

shouldn't it automatically start on the port variable defined earlier?

What do you mean by this?

proccess.env.PORT that's how you access env variables

KrishangOP•2y ago

When defining the port variable, we give it 2 choices right? a number.. 5000 in my case, or process.env.PORT which is an env variable, since they are predefined, the app will always use them, instead of "0.0.0.0"

0.0.0.0 is the host

LaCrak27•2y ago

app.listen(process.env.PORT, () => {
  console.log(`SSAPI active, listening on port ${process.env.PORT}.`)
})

app.listen(process.env.PORT, () => {
  console.log(`SSAPI active, listening on port ${process.env.PORT}.`)
})

the port is seperate from that.

LaCrak27•2y ago

i just do this lmao 0.0.0.0 is the ip adress, and the port is something completely unrelated

ohh 😅

LaCrak27•2y ago

ye, dw

KrishangOP•2y ago

A little dumb of me, but it's working now.. I looked closely and it was a matter of preference

LaCrak27•2y ago

perfect then

KrishangOP•2y ago

The docs say I should prioritize the env variable And not the hard coded port number

LaCrak27•2y ago

yeah

KrishangOP•2y ago

It's working now! Thanks for all the time and help!!
