A QuickBooks user may get QB Error code 6175 0 when he or she is trying to host QB company file for multi-user access. This error can arise if multi-user sharing setting is misconfigured, or if a security software such as a firewall is blocking communication.

QuickBooks Error 6175 is displayed on the screen with the message that QuickBooks is trying to access the company file but the database server is not responding. This happens when you try to host multi-user access for your company file.
