• Go to your Windows Firewall Open control panel and in the search bar, type Firewall, and press Enter from your keyboard.
• Open the Windows Firewall and click on Advanced
• On the Left side of your window, select Outbound rules and right-click on it.
• Select New Rule

• Go to the TCP option and enter the following port for the specified local ports box:
  • For QuickBooks Desktop 2018: 8019, 56728, 55378-55382
  • For QuickBooks Desktop 2017: 8019, 56727, 55373-55377
  • For QuickBooks Desktop 2016:8019, 56726, 55368-55372

Method 4: Add Some Firewall Exceptions

• Type in firewall in the start and then click on Windows Firewall.
• Now click on the advanced settings tab.
• Now create the firewall exceptions. For this click on the inbound rules once you click on the inbound rule click on the new rule on the right side.
• Click on the new rule on the right-hand side and then select port.
• Select the radio button with sales for it and then hit next.
• Now we will have to add the particular ports for that particular version of QuickBooks so depending on your version the port numbers will differ.
• Since I’m using 2013 I will copy and paste the port numbers for 2013.
• Please make sure that the port numbers are always separated by commas. And consecutive ports are separated by a dash.
• So just go in and copy the ports in the standard format and paste them into the space provided. Make sure that you have TCP selected.
• Now hit next then click on allow the connection. Make sure that the radio button that says allow the connection is checked and make sure that you have a checkmark on all three of them.
• Now give it a name like QB ports or just a name to identify it and click finish.

Thus now that we have added inbound rules, our next step will be to add outbound rules. Once both the rules have been defined on the main computer, you will have to perform all the necessary steps on all the other computers on which you use QuickBooks.

Once you are done with all the necessary action then i.e.

• Adding firewall ports
• Inbound rules and
• Outbound rules

You are now able to fix your issue. Your next step will be to login back into your QuickBooks accounting software and perform the same action which was earlier giving you QuickBooks error H202.
