I'm trying to connect 2 services together using private network but I can't seem to reach it using the railway private domain.
I have a service (crawl4ai) running on port 11235
This is from the service deployement logs: [2025-11-20 14:33:39 +0000] [3] [INFO] Listening at: [http://0.0.0.0:11235](http://0.0.0.0:11235) (3)
I'm trying to reach that service from an other service using basic curl:
If I try the same command using a public url, I get no issue.
How can I connect to this service on the private network ?

Hi,
You need to bind your service to both IPv6 and v4 for private networking and public networking to work. What framework are you using?
ultimately I won't need public networking on the crawl4ai service. I'm using nodejs service on 1 side and crawl4ai (python) on the other side

Then you can just bind to IPv6.

Right now you are using IPv4

Using :: as the host should work
