What causes Avast Firewall Blocks QuickBooks issue?
There are two possible triggers. We have listed them below for your reference:
Closed Ports: This error arises when the particular ports that are used by the application to use the Internet are not accepted by the computer. The particular ports accessed by the application should be passed by the given user in order for the application to function systematically. In contrast to other applications, QuickBooks never uses different ports, but a particular port is based on the application version that you are accessing.
Blocked by Avast Firewall: In a few cases, the application can get blocked by the Avast firewall. In some cases, it can also be that a third-party antivirus program has restricted the application permanently.
Now, when you have a decent knowledge about the problem and its elements, let’s move on to fix it.
