Solution 1- Add special ports for QuickBooks in Windows Firewall settings

The software may encounter performance issues if this process stops running in the background. This can happen if Windows Firewall places restrictions on QuickBooks processes and terminates them while running. A simple way to solve the problem is by configuring the firewall settings and adding some QB ports to prevent software blocking. Apply these steps –

  1. Just click on the search bar on your taskbar and type “Windows firewall”.
  2. Click New Rule and select Port before tapping Next.
  3. You will see two options on your screen – UPD and TCP. Select TCP and go to the Specific Local Ports option.
  4. Use the list below to select the ports for your QuickBooks by year version-
    QuickBooks Desktop 2017:8019, 56727, 55373-55377
    QuickBooks Desktop 2018:8019,56728,55378-55382
    QuickBooks Desktop 2019:8019, XXXX
    QuickBooks Desktop 2020 and latest:8019, XXXXX.
  5. Click Next after selecting the correct port for your QuickBooks.
  6. Click Allow the connection and click Next.
  7. Create a new rule with any desired name and click the Finish option.
