Please refer to Private Networking docs here: https://docs.railway.com/guides/private-networking

Would also check that the private URL is correctly set and the application is configured to resolve IPv6 addresses

Finally, would make sure all services are within the same project and environment.

Thanks,

David

Hi @david, during docker-image build if i try to connect railway internal variables then won't work right?

The private network is indeed not available during build.

Thanks for confirmation, my-app is trying to connect to mongodb with internal-variable during docker-build

that's why it's failing!
