Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to www.youtube.com because this website requires a secure connection. What can you do about it? www.youtube.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. The issue is most likely with the website, and there is nothing you can do to resolve it. If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

Warning: Potential Security Risk Ahead

My university website (brightspace) is blocked by "Warning: Potential Security Risk Ahead" and clicking advance does not allow me to continue. I was using brightspace when it suddenly became blocked and I have received errors stating it was an HSTS error to now an expired certificate. I have tried to restart Firefox and clearing the website from my history and clearing cache, but nothing worked so far. Accessing this website has only been an issue on my Firefox on my laptop. The website's servers is not having issues, my other devices can access it flawlessly, and using other web browsers on my laptop does not cause any issues. I would like not to switch my browser, so any help to accessing this website would be greatly appreciated

On some of my accounts that I use every day I keep getting unsecured site and can't advance to my site. Michales is one of them so I can't use my coupons to buy my products.
