Hello Team,

I am currently hosting a Node.js backend with a MySQL database on Railway. The deployment is successful, and the APIs are working correctly in some environments.

However, I am facing a critical issue:

• The API works when accessed from certain networks/devices.
• But it does NOT work when accessed from:
  • Jio mobile network
  • WiFi connections (multiple tested)

In these cases, the request either:

• Times out, or
• Fails to connect to the server

Details:

• Backend: Node.js (Express)
• Database: MySQL (Railway hosted)
• Deployment status: Successful
• Public URL: https://graceful-prosperity-production.up.railway.app/health

What I have verified:

• The service is running and accessible from some networks
• No application-level errors in logs
• Routes are correctly defined
• CORS is configured (if applicable)

Concern:

This appears to be a network accessibility or routing issue rather than an application bug.

Request:

Could you please check:

1. If there are any IP restrictions or regional/network-level blocks affecting access
2. If Railway services are fully accessible across all ISPs (especially Jio India)
3. If there is any issue with public networking, DNS, or edge routing

This issue is impacting real users who are unable to access the API from mobile and standard WiFi networks.

Looking forward to your assistance.

Thanks & Regards,

Paramjit Singh
