All on one server.

There is only one server. Everything is on one server. There shouldn’t be any network issues, right?

I used the CDC binary file ./cdc to start with the file address. Using the extended command again doesn’t work. Changing to a different address works.

If the ports are not accessible, first check if the network is connected, then check the ports and services.
