Event ID: 8088
Event Description: The Managed Metadata Service 'Managed Metadata Service' is inaccessible.
Not a very detailed error. ULS does not expand on the error either. I ensured that the MMS Service Account has full control to the service. I also put the account in the Term Store Administrators but that did not fix the issue. I reset the MMS on all servers in the farm as well, no luck.
