Quick Fixes to Resolve Error Code H202 in QB Desktop 

Configuring firewall port settings for QuickBooks involves allowing inbound and outbound communication through specific ports to facilitate connections between QuickBooks and the server hosting the company file.

Solution: Configuring the firewall port settings on your system correctly

One of the easiest ways to quickly fix the problem is to configure your firewall port settings on your system. This will be of real help, so just follow the steps given below.

• QuickBooks uses several ports for communication, but the most common ones are: 
  • QuickBooks Desktop 2019 and later: TCP ports 8019, 56728, 55378-55382
  • QuickBooks Desktop 2018 and earlier: TCP ports 8019, 56727, 55373-55377

Note: If you’re using a specific version or hosting setup, consult QuickBooks documentation for the exact port numbers.

• Open your firewall software or security settings. This could be the built-in Windows Firewall or a third-party firewall program.
• Navigate to the inbound rules section of your firewall settings. Specify that the rule should allow inbound traffic. Ensure the rule applies to TCP protocol.
• For simplicity, set the rule to apply to all profiles (domain, private, public), or customize it based on your network setup.
• Some firewalls allow you to specify the program or executable file instead of ports. If your firewall offers this option, choose QuickBooks and allow it to communicate through the firewall.
• In addition to firewall settings, ensure that network settings such as IP addresses, DNS configurations, and network sharing permissions are correctly set up to allow QuickBooks communication.
