Hi Railway Team,

I'm facing an issue where my Railway-hosted backend is inaccessible only for users on Jio Mobile Data and JioFiber in India.

Project Details:

Issue:

  • The application works perfectly on Airtel, BSNL, ACT and other ISPs.

  • On Jio Mobile Data and JioFiber, both the Railway public domain and the custom domain fail to load.

  • Chrome shows:

    DNS_PROBE_FINISHED_NXDOMAIN

Observations:

  • The application is deployed successfully.
  • No deployment or runtime errors are present.
  • SSL is configured correctly.
  • The custom domain is verified and connected in Railway.
  • DNS records are correctly configured in Hostinger.
  • Since even the Railway public domain fails on Jio, this appears to be a DNS resolution or routing issue rather than an application issue.

Could you please verify:

  1. Whether there is any known DNS/routing issue between Railway and Jio (India)?
  2. Whether the Railway public domain is correctly propagated globally?
  3. Whether there are any IPv6 or edge network issues affecting Jio users?

This issue is affecting all customers using Jio, making the application inaccessible for them.

Please let me know if you need any additional information, logs, or DNS records.

Thank you.

Jio is most likely blocking Railway generated domains. In that case, you have to use a VPN to access your service. Your custom domain is working, although, you have an invalid TXT record. The value after "railway-verify=" must be exactly 64 characters, but yours contains 80. So, it's worth fixing that. If users can't access the custom domain, it could be related to caching issues.
