Newsfeed error - The operation failed because the server could not access the distributed cache.

Question

Recently installed SharePoint 2013 RTM, on the newsfeed page an error is displayed, and no entries display in the following or everyone tabs.
"The operation failed because the server could not access the distributed cache."
Reading through various posts, I've checked:
- Activity feeds and mentions tabs are working as expected.
- User Profile Service is operational and syncing as expected
- Search is operational and indexing as expected
- The farm was installed based on the autospinstaller scripts.
- Don't believe this to be a permissions issue, during testing added accounts to the admin group to verify
Any suggestions are welcomed, thanks.
The full error message and trace logs is as follows.
SharePoint returned the following error: The operation failed because the server could not access the distributed cache. Internal type name: Microsoft.Office.Server.Microfeed.MicrofeedException. Internal error code: 55. Contact your system administrator
for help in resolving this problem.
From the trace logs there's several messages which are triggered around the same time:

Thanks Thuan,
I've restarted to the Distrubiton Cache servicem and the error is still occuring.
The AppFabric Caching Service is running under the service apps account, and does appear operational based on:
