Hello,
I am pretty new to Railway and have been unable to fix the following 502 bad gateway error.
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.

The build/deploy logs are clean. Please help!

Try logging the variable your application is listening on console.log(process.env.PORT) for example, and map that port to your URL in service settings > networking.

Make sure your application is listening on the same port your URL is mapped to.

Good morning. I have genealogy software. Java 21 and MySQL 8 configuration. I can't put it in the cloud. Thank you. Jose

I am semi-certain that I did so, however, the error persists. I've got the port mapped to $PORT variable. Is that correct?

make sure your app listening to address 0.0.0.0 instead of localhost or 127.0.0.1

Try logging the variable your application is listening on `console.log(process.env.PORT)` for example, and map that port to your URL in service settings > networking.
