You are getting a false positive.

Are you using Nortons or McCaffeys by chance? If so, I suggest you get a different firewall because those 2 are notorious for having "issues"

You can try adding the web address to your firewall's safe list and see if that helps.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
