The solution that you can pick while trying to fix this problem on your system.


Solution: Try adding exceptions to Windows Firewall ports for your QB app


Adding exceptions to Windows Firewall ports for QuickBooks involves configuring firewall settings by allowing specific communication between QuickBooks and the network.


  • Determine the ports that QuickBooks uses for communication. The default ports include 8019, 56728, 55378-55382.

  • Press the Windows key, type "Firewall," and select "Windows Defender Firewall" from the search results.

  • In the left pane, click on "Advanced settings." This opens the Windows Firewall with the Advanced Security window. 

  • In the left pane, right-click on "Inbound Rules" and select "New Rule.” Select "Port" and click "Next." 

  • Choose "Specific local ports" and enter the ports used by QuickBooks (e.g., 8019, 56728, 55378-55382). Click "Next." Select "Allow the connection" and click "Next."

  • Choose when this rule applies (Domain, Private, Public). Typically, you'd want to select all three. Click "Next."

  • Provide a name for the rule (e.g., QuickBooks Ports) and an optional description. Click "Finish."

  • Follow the same steps to create outbound rules by right-clicking on "Outbound Rules." In the Windows Firewall with Advanced Security window, confirm that the new inbound and outbound rules for QuickBooks are listed.

  • If you're unsure about the ports QuickBooks uses, check the QuickBooks documentation or contact QuickBooks support.

  • If you're on a network with multiple computers, ensure that these firewall changes are applied to all relevant machines.

  • Keep firewall settings secure. Only open necessary ports and protocols.

  • If you have a third-party antivirus or security software, ensure it's not conflicting with Windows Firewall.
