Hi, It seems that I cannot add any hosts using Custom option. This is the setup: I have a host called andonmaster and it’s running the rancher. Then I have one host named dockerregistry which I want to add to rancher. But this simple job seems to be too hard for me or for our env… We have our own cloud where we must use domain names. Is that somehow the factor? IMO the iptables are ok in both hosts… **@andonmaster:~$ sudo iptables -L** [sudo] password for makelkal: Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT)

This looks a lot like this issue: [https://github.com/rancher/rancher/issues/1147](https://github.com/rancher/rancher/issues/1147) Basically, if you have some containers on your host that were deployed using Docker 1.5, the containers are causing issues when deploying Rancher on a later version of Rancher. You can fix this by stopping and removing the containers deployed using Docker 1.5. Basically, the concept of labels on Docker images/containers changed, which caused issues. ---

Thanks Denise for answering, but I’m quite sure that Docker 1.7 is the oldest version that these hosts have ever had installed. Now I have: **@andonmaster:~$ docker version** Client: Version: 1.8.1 API version: 1.20 Go version: go1.4.2 Git commit: d12ea79 Built: Thu Aug 13 02:35:49 UTC 2015 OS/Arch: linux/amd64 Server: Version: 1.8.1 API version: 1.20 Go version: go1.4.2 Git commit: d12ea79 Built: Thu Aug 13 02:35:49 UTC 2015 OS/Arch: linux/amd64 **@dockerregistry:~$ docker version** Client: Version: 1.8.1 API version: 1.20 Go version: go1.4.2 Git commit: d12ea79 Built: Thu Aug 13 02:35:49 UTC 2015 OS/Arch: linux/amd64 Server: Version: 1.8.1 API version: 1.20 Go version: go1.4.2 Git commit: d12ea79 Built: Thu Aug 13 02:35:49 UTC 2015 OS/Arch: linux/amd64 ---

Hi, I got it to work. The reason was that my iptables was not reloaded… Sorry for inconvenience! Lessons learnt: If the error says that connection is refused, it usually is 😄 Thanks! Kalle ---
