Why do I get the infrastructure error for login failures?

First SQL Query as text for the next poor fellow who finds this post 😄

SELECT        spm.class_desc, spm.permission_name, spm.state_desc, spr.name, spr.type_desc, spr.is_disabled, ep.name AS EndpointName, ep.protocol_desc AS EndPointDescription, ep.state_desc AS EndPointState, ep.type_desc AS EndpointType
FROM            sys.server_permissions AS spm INNER JOIN
                         sys.server_principals AS spr ON spm.grantee_principal_id = spr.principal_id LEFT OUTER JOIN
                         sys.endpoints AS ep ON spm.major_id = ep.endpoint_id
