• Firewall or antivirus blocking QuickBooks ports

  • QB 2022: 8019, 56729, 55383–55387

• Add QuickBooks and Database Server Manager as allowed applications

• Restart the system and retry access

4. Check Folder Permissions on the Server

5. Use QuickBooks File Doctor via Tool Hub

QuickBooks Tool Hub is a free utility that helps resolve network and file-related errors.

• Delete the file

• Reopen QuickBooks and try accessing the company file—it will auto-create a new one.

Check if the server is reachable:

• Press Windows + R, type ping [ServerName], and press Enter
