I have a backend developed in Swift / Vapor that exposes en GRPC server for my mobile app. In staging environment, with the railway proxied domain and port, it works great. But in production I wanted to setup a custom domain, but it doesn't work (GRPC Error : deadlineExceeded) . I'm not sure if it's because of the custom domain name or something else (I'm a mobile developer, and backend / infra is quite new for me 😇)
