Error like this occur when QuickBooks tries to connect to your Internet Explorer, Glen.

QuickBooks Desktop uses Internet Explorer to open and display most of its windows. To make sure it won't happen again, we can try configuring your Internet Explorer (IE). Before that, let's make sure to make IE as the default browser. 

Then:

1. Open your Internet Explorer.
2. From the Command Bar, select Tools.
3. Select Internet Options, then select the Security tab.
4. Click Trusted Sites, and click on Sites.
5. In the Add, this website to the zone field, enter *.intuit.com and click on Add.
6. In the Trusted sites window, uncheck Require server verification.
7. Close the Trusted sites window, and uncheck Enable Protected Mode.
8. Close the browser.

We can configure also your firewall security settings for Desktop. This is to make sure that the internet access will go through without any problems.
