Application frontend is seeing CORS issue, it is working in the morning.
I created a custom domain and configured it properly. It is protected by cloudflare. It is working fine. I reverted custom domain configuration

Did you add the custom domain to your CORS rules?

Yes I did in railway app variables, anyother place to define the cors rules?

You should be configuring CORS in your backend service, not just through environment variables. (Unless your backend CORS value relies on variables?)

thanks I'll implement CORS in backend, I can use 443 as custom port for custom domain right?

The port depends on whatever port your application is listening on.
