Two restarts from the wordpress pod smells trouble with the app itself.
Anyway you can check the service definition is correct by oc get pod and them oc describe pod wordpress-xxxx (whatever you see in oc get pod). Check if the pod has a label name=wordpress. I guess it should be ok as the service as one Endpoint.
10.1.0.11 should be your wordpress-xxxx pod IP address (from oc describe pod). Try to connect directly to that pod address, instead of the route. This should work from any node or from the master. You can use curl or elinks if you do not have GUI on those hosts.
If connecting directly to the pod works, try connecting to the service ip address (172.30.117.249)
Sorry I am giving only general troubleshooring steps, and sorry if those are already known to you.
