Hello Railway Support Team,

My Android application cannot connect to my Railway backend.

When I run the app on Android (via Android Studio or APK), the request to my Railway service fails.

Important details:

Project name: fateness

Environment: production

Service domain (auto-generated by Railway):

fateness-production.up.railway.app

The same domain works in browser, but fails only inside Android, showing connection/SSL issues.

I am not using any custom domain now — only the default Railway domain.

Please check if there is an issue with certificate, networking, or port exposure on your side that prevents Android from reaching the service.

Thank you!

Hi again.

The links you sent do not solve my issue.

I need help with a different problem:

My Android app (built with Android Studio / Capacitor) cannot reach my Railway backend domain.

The domain works in browser, but inside the Android app it fails completely.

My service details:

Project: fateness

Service: fateness (production)

Railway default domain: fateness-production.up.railway.app

No custom domain is used

Error on Android:

Connection fails

SSL certificate / handshake error

Works only in browser, not inside Android WebView

I need Railway to check if there is any SSL, certificate, networking, or port issue on your side preventing Android from connecting to the default domain.

Thank you.
