Our Railway-hosted application does not load on an iPhone over mobile internet, including when opened directly in Safari. Internal health checks pass, and the application responds from another network. Redeploying did not resolve the affected connection.

Are there any known public-network routing or reachability issues? What is the safe way to provide service-specific diagnostics privately to Railway staff on the Hobby plan?

Please advise the minimum information needed. We prefer not to publish application addresses, account identifiers or detailed logs.
