Hello,

I'm experiencing a critical issue with my service VINC-WMS in the production environment. The service is returning a 502 Gateway error when accessed via custom domain wms.myphamminhphuong.com.vn.

Issue Details:

When attempting to retrieve the service configuration, I received the following error:

Invalid enum value. Expected 'us-west2' | 'us-east4-eqdc4a' | 'europe-west4-drams3a' | 'asia-southeast1-eqsg3a', received 'asia-southeast1'

The service's region configuration is set to asia-southeast1 (invalid), but Railway only accepts asia-southeast1-eqsg3a.

Service Information:

• Project ID: 745fc2cb-7561-41f8-960f-b11bcae57595

• Environment: production (df876d87-15ef-4705-854f-3bee705b3026)

• Service Name: VINC-WMS

• Service ID: 28876b9f-18fe-45b8-9485-d68eb9c118ef

• Custom Domain: wms.myphamminhphuong.com.vn (configured with green checkmark ✓)

• Current Status: Online but returning 502 Gateway errors

What I've Done:

• Verified custom domain DNS configuration (CNAME: 0cr4czlg.up.railway.app) — configured correctly with green checkmark

• Confirmed the application is running and listening on port 8080

• Restarted the service multiple times

Request: Please fix the region configuration from asia-southeast1 to asia-southeast1-eqsg3a so the service can function properly and respond to requests via the custom domain.

Thank you for your assistance.
