Many 8088 warnings in Application log

Question

On a client's SharePoint 2013 server I see a lot of 8088 warnings that say "The Managed Metadata Service 'Managed Metadata Service' is inaccessible."
I looked it up and found only SP 2010 responses. But they all indicate a permissions problem. As far as I know, no permissions have been changed. I followed the TechNet article for SP 2010 and found the application pool and the account for it. I then
checked permissions but the account was not listed, only something called Local Farm. I don't know what that is even though it had all 3 permissions checked. So I added the domain account listed for the application pool and gave it all permissions shown. But
I'm still getting the warnings.
Any ideas on how to proceed from here?

Hi  Jonathan,
The  warning can occur if the server is offline or the managed metadata service is not started or has been disabled. The service might not start if the application pool account does not have sufficient
permissions to the term store.
Resolution:   Verify the application pool account permissions:
Verify that the user account that is performing this procedure is a member of the Farm Administrators group.
On the Central Administration Home page, click Application Management.
On the Application Management page, in the Service Applications section, click Manage service applications.
On the Service Applications page, in the Type column, click the managed metadata service application, and then click Properties.
In the Create New Managed Metadata Service dialog box, in the Application Pool section, record the name of the application pool and the application pool
account name.
Click Cancel.
Log on as a member of the local Administrators group.
In Central Administration, on the Service Applications page, in the Type column, click the managed metadata service application, and then click Permissions.
Confirm that the account that you recorded in step 5 has one of the following permissions:
Read Access to Term Store
Read and Restricted Write Access to Term Store
Full Access to Term Store
