Project
My Java Spring Boot Maven application:
GitHub: https://github.com/Pepin4/NaturoApp
Hosted on Railway: naturoapp.up.railway.app
Issue
My app builds and deploys successfully — no errors in the build or deploy logs.
However, when I open the main page, I get this error:
Application failed to respond
Request ID:iJUa4xtKRfeZWcYIg5js2Q
These are the logs I see from the Railway proxy:
Railway log examples (2 entries)
Log 1: /favicon.ico — Status: 499
{
"method": "GET",
"path": "/favicon.ico",
"httpStatus": 499,
"responseDetails": "client has closed the request before the server could send a response"
}
Log 2: / — Status: 502
{
"method": "GET",
"path": "/",
"httpStatus": 502,
"responseDetails": "failed to forward request to upstream: connection refused"
}
What I’ve checked so far
The app builds with mvn clean package- Port 8080 is used (default in Spring Boot)
- My
pom.xmlincludesspring-boot-maven-plugin 
No Procfileyet (Railway auto-detects Maven projects)
Possible causes
Maybe Railway is not correctly detecting the
.jarfile?Should I add a Procfile like:
web: java -jar target/NaturoApp-0.0.1-SNAPSHOT.jar?Could there be a misconfiguration in my
application.propertiesor port setup?
Asking for help
I’ve been stuck on this issue for over a week now.
Any help or guidance to diagnose why Railway can’t seem to detect and launch my Spring Boot app would be greatly appreciated
System info
Java 17
Spring Boot 3.2.5
Maven
No database yet (simple REST API)
Railway free plan
Thanks in advance to anyone who takes the time to help

The github repo you provided is private so i cannot review the code.
To me this looks like a networking issue where the application is listening on a different host/interface. Spring by default listens on localhost:8080 so this means it's only accepting connections from within that same container on the localhost interface.
When railway tries to connect to it, it can't and that's why you get a connection refused 502 response.
Change the server address/host in your code to 0.0.0.0

in your application.properties
set server.address=0.0.0.0
then do mvn clean package

its public 
For the following solution, I had already tried it, but it didn't change anything.
Still, I’ve added the line again based on your suggestion.

The actual clickable link is different in your original post. try it
The way you're trying to access the environment variable for the port is nodejs syntax. For spring boot application.properties
do server.port=${PORT:8080}

It wasn’t using process.env this morning — I had just forgotten to remove it after a test.
So no, unfortunately, that’s not the solution.

Is the deployment failing after successful build or simply not responding ?
Can you post your full deploy logs ?

I see that you have redis as a dependency in pom.xml but you are not actively using it.
As a result logs show that spring's auto-configuration for Redis is triggering.
Could you comment out the redis dependency part ?<dependency>

One solution would be to try, if possible, to change the Spring version, as it no longer offers support at the current date.
I've had problems with this here.

Unfortunately, this did not resolve the issue. Given the urgency, I decided to switch to another platform that also allows free hosting of this project.
Although the page loading speed is significantly limited, it remains sufficient for the immediate needs of my application.

So it works on koyeb but not on railway with the same code ?
Would you like to try dockerfile deployment ? I can open up a pull request with the file.

I went ahead and created a Dockerfile
Then created a docker container for the app and mysql locally and it ran successfully.
Could you review the pull request and give railway deployment another try ?
