Quickbooks software cannot communicate due to firewall issue

I've got you covered, mburh. We can rectify the error you received to get you back to business with QuickBooks Desktop (QBDT).

The error usually means your network firewall is interrupting the connection. Here's how to fix firewall errors so you can get back to work. Before we start, let's secure a backup of your company file to reinstate your accounting data if you ever run into a problem with it. After that, download QuickBooks Tool Hub and run QuickBooks File Doctor to run a mini repair of your server and firewall. Here's how:

1. Download and install the latest QuickBooks Tool Hub.
2. Once installed, open the tool hub and go to your Company File Issues.
3. Click Quick Fix My File.
4. Select OK when it completes and launch your QuickBooks.

Once done, run QuickBooks File Doctor by referring to Step 3: Run QuickBooks File Doctor in this article: Fix company file and network issues with QuickBooks File Doctor.

If you're still seeing an error after following the steps above, proceed to update your QuickBooks to the latest release. If you get the same error, proceed with the suggested fixes from Step 3: Check your firewall settings to Step 6: Turn off hosting on your workstations if needed in this article: How to fix "Error: Cannot communicate with the company file due to firewall"
