Can't access pod running on the node from the master

I have installed openshift 3.1 on two virtual servers and created the hello-openshift pod running on the node.
When I try to access the application (curl http://10.1.1.3:8080) I get "curl: (7) Failed connect to 10.1.1.3:8080; No route to host" on the master.
The address "10.1.1.3" is the one listed by "oc describe".

Running the command "curl http://10.1.1.3:8080" on the node gets the expected uotput: Hello OpenShift!

I'm trying to follow the course material for DO280-OSE3.0 but have installed version 3.1 instead of 3.0.

Any ideas what may be wrong?
