When QuickBooks and the server housing the company file are unable to connect, a QuickBooks Network Connection Failure occurs. Incorrect firewall configurations, network problems, or disturbances in the database server manager may be to blame for this. Users may see errors such as H202 or H505, which impede access to multi-user mode. In order to fix the problem, it is usually necessary to verify that the QuickBooks Database Server Manager is operating correctly, configure firewall settings, and verify network connectivity.
