I am facing a connectivity issue with Railway-hosted deployments using the default Railway domain (*.up.railway.app).

The deployed application works perfectly on:

• Wi-Fi networks

• Other ISPs/mobile networks

However, the website does not open on Jio mobile data. Multiple users in India are facing the same problem, specifically with Jio connections.

Observations:

• Deployment status is healthy and running

• The issue occurs only on Jio network

• Other networks load the same URL normally

• Affected domain pattern: *.up.railway.app

Based on community discussions, this appears to be a DNS resolution or ISP-level blocking issue affecting Railway domains on Jio network, not an application or deployment error.

Kindly investigate whether there is a networking or routing issue between Railway infrastructure and Jio ISP, or suggest an official workaround or fix.

This issue impacts a large number of Indian users since Jio has a significant user base.

Thank you for your support.
