I am trying to install UCP in RHEL 7.2 UCP installation went well.But DTR installation is failed with below error…Though We have disabled firewall and Selinux in UCP and DTR server.Even we have tried to use --replica-http-port and --replica-https-port and got the same error message
[root@test4 ~]# docker run -it --rm docker/dtr install --ucp-url https://10.126.40.227 --ucp-node test4 --dtr-external-url 10.126.40.243 --ucp-username admin --ucp-password xxxxxx --ucp-ca "$(cat ucp-ca.pem)"

ERRO Make sure that there is a node in your UCP cluster where port 80 and port 443 are open. Also confirm that all UCP node have the DTR images or can obtain them from Docker Hub.
