This reply took a while, but I wanted to run with my change for a period of
time before posting what I learned...
Every time the browser had an issue, I noticed that the Phishing Filter

So, I disbaled the phishing filter in the Internet Options, under the
Advanced tab.
After that, I have not had a problem since.
