I am using the rancher image on docker using ssh onto a local machine. On adding a new custom host, although the terminal command gets executed successfully, I still cannot see a host in the ui.

> [@Swapnil\_Pandey](#): > > NFO: ENV: CATTLE\_URL=[http://192.168.0.245:8080/v1](http://192.168.0.245:8080/v1) > INFO: ENV: DETECTED\_CATTLE\_AGENT\_IP=172.17.0.1 It looks like this might be the problem. On your host, you are using a 172.17 address, but your Rancher server is using a 192.168 network. What is the docker run command you are using on the host? Do you specify the CATTLE\_IP option as the 192 IP? ---
