Getting content from cluster from the second follower causes an "AskTimeoutException"

Attempting to fetch data from the second follower in a 3-node cluster when original owner is down, causes a java exception to be returned in the response text:

<errors xmlns="urn:ietf:params:xml:ns:yang:ietf-restconf"><error><error-type>application</error-type><error-tag>operation-failed</error-tag><error-message>Problem to get data from transaction.</error-message><error-info>akka.pattern.AskTimeoutException: Ask timed out on [Actor[akka.tcp://opendaylight-cluster-data@10.29.11.243:2550/user/topology-netconf/netconf-test-device/mountpoint#1234942408]] after [5000 ms]

The response code returned is 500.
The URI requested was: /restconf/config/network-topology:network-topology/topology/topology-netconf/node/netconf-test-device/yang-ext:mount

The request is successful when the first follower (the new owner) is querried
