  • Incorrect folder permission may hinder the company file folder from being shared, contributing to connection errors. 
  • QBDBMgrN not functioning in the background of your system. 
  • Server configuration issues or connectivity problems with other workstations in the particular network can trigger the communication problem in QuickBooks. 
  • The outdated QuickBooks Desktop application not only causes company file connection errors but is also accountable for various other errors like payroll errors, printing errors, update errors, and banking errors.
