SharePoint 2013 Managed Metadata Service KeyNotFoundException


Getting this error on a SharePoint 2013 farm when trying to access term store:

Failed to get term store for proxy 'Managed Metadata Service'. Exception: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

Looks like the most common way to solve this is to recreate your managed metadata.

I did a little investigation. And nothing worked.

At the end i just recreated it...

Be sure to have a backup.

Detach The metadata DB
Delete and then recreate the managed metadata service application.
Attach the old DB and in the metadata settings point to it.
