I’ve deployed my first Streamlit app using a custom domain (yt-insights.datatransformer.in) on Railway, but the application fails to respond after deployment. The error message indicates the application failed to start. I’ve configured correct start command (streamlit run app.py). Please assist with resolving this issue.
Setup is complete:
Public Networking
Access your application over HTTP with the following domains
yt-insights.datatransformer.in
Setup complete
Yet getting this error:
Application failed to respond
This error appears to be caused by the application.
If this is your project, check out your deploy logs to see what went wrong. Refer to our docs on Fixing Common Errors for help, or reach out over our Help Station.
If you are a visitor, please contact the application owner or try again later.

streamlit run app.py is not the best start command, please see here for the optimal start command.
Once you have made those changes your app should start to work from the custom domain.

I think the issue is with A record and CNAME, any guidance on that should help me. Thank.

You need to use a CNAME, You would need to use Cloudflare as a nameserver - https://developers.cloudflare.com/dns/zone-setups/full-setup/setup/
