Windows 10 with Docker - Host is unreachable remote dataset


i have installed xibo on my Windows 10 machine with docker. I can’t connect to my remote dataset. The log says:
Host is unreachable!

I connected me with the cms container via docker exec -it xibo-docker_cms-web_1 /bin/bash
Our network is The IP Adress of the CMS Docker Container is without DNS.
How can i configure it correctly? Thanks
