The initialization of the CRM authentication pipeline execution has failed for org Org Name with a sql error:

Hi I am getting the following error in my CRM app server, something went wrong on the SQL server.

error message below;

The initialization of the CRM authentication pipline execution has failed for org crm-mbtgroup.tarsus.co.za with a sql error: Server: TJHBCRMSQL01, Exception: System.Data.SqlClient.SqlException (0x80131904): Invalid column name 'TraversedPath'. Invalid column name 'PositionId'.

any Idea how I can fix this error. My server doesn't browse, throwing a 404 error. This is CRM version 2013. everything worked fine before and nothing changed out of the ordinary
