My service is healthy and repeatedly starts successfully on port 8080, but the generated Railway public domain does not resolve.

Service: cultstore-budget-flow

Environment: production

Generated domain: cultstore-budget-flow-production.up.railway.app

Observed on May 11, 2026

Browser error: DNS_PROBE_FINISHED_BAD_CONFIG / server IP address could not be found

Evidence:

- deploy logs show “CultStore Budget Flow running at http://localhost:8080”

- local app works

- tested on mobile data too

- deleted and regenerated the Railway domain, but the new generated domain still does not resolve

Your domain cultstore-budget-flow-production.up.railway.app is resolving correctly from the public internet, and your latest deployment shows as successful. The DNS_PROBE_FINISHED_BAD_CONFIG error is likely caused by a stale DNS cache on your local machine or network, possibly worsened by deleting and regenerating the domain. Try flushing your local DNS cache (ipconfig /flushdns on Windows, sudo dscacheutil -flushcache && sudo killall -HUP mDNSResponder on macOS), then test in an incognito window or try a different DNS resolver like 1.1.1.1 or 8.8.8.8.

I already tested on mobile data as well, not just my local machine, and the generated Railway domain still does not resolve.

The service is healthy and deploy logs show:

“CultStore Budget Flow running at http://localhost:8080”

This issue was observed on May 11, 2026.

Please escalate to support because this does not appear to be a local DNS cache issue.
