QuickBooks Desktop 2018: “8019, 56728, 55378-55382”
QuickBooks Desktop 2019: “8019, XXXXX”
QuickBooks Desktop 2020: “8019, XXXXX”

Please Note: For QuickBooks Desktop 2019/2020/later versions, a dynamic port is used. In the “Start Menu”, you can find “QuickBooks Database Server Manager” and open it. Via the tab of Port Monitor, pick the QB version. Then jot down the “Port Number”. Its format should be mentioned as “8019, XXXXX” where the dynamic port number is represented by “XXXXX”. Use this number for port exceptions.

  • Tap on “Next”.
  • Click on “Allow the Connection”.
  • Press “Next”.
  • Choose every profile when prompted to do so.
  • Tap on “Next”.
  • After making a rule, enter “QBPorts(Year)” as the name.
  • Press “Finish”.
  • Do all the steps again but this time you have to choose “Outbound Rules” as the fifth step.
  • Then run “QuickBooks Desktop”.
  • Ensure that the “Multi-user Mode” is on. Additionally, you can run the software using the host PC’s network.

If the H202 error in QuickBooks 2019 or another version is observed, make firewall exceptions for the QB programs.

It is super easy. I only used one method and the error got fixed. So happy to read this blog. It has so much to read but surprisingly I didn’t need to read much as the first two methods were enough for me.

I am a newbie to using the QuickBooks program and viewing an H202 error was very scary for me. My internet connection was completely fine but I had to set the hosting to local files and it worked for me. Now there are no annoying errors on my screen.

Actually, I often read about QuickBooks just to be more aware. It was long back when I randomly found what the QuickBooks error H202 is. Since I was already aware of why it occurs, I was able to troubleshoot it much quickly.

The Quickbooks error h202 might seem to be something very big. But it can be sorted in very simple ways. I don’t know whether all of these fixes will work but a few of them certainly did when the error was there in our computer systems.
