I get a "secure connection failed" error when trying to access www.treasurydirect.gov from the latest version of Firefox. Similar message when I use Chrome and Safari. Tried deleting browsing history and cache, still did not work. Called Treasury Direct customer service, they insisted that the problem is with my ISP, HughesNet. Skeptical, I went to a coffee shop with a different ISP and was able to access the Treasury Direct site with no problems.
What do I need to do to be able to access treasurydirect.gov without going to the coffee shop first? Thanks.
