"cant establish secure connection" for a single website

[AC Question]

While ive been reading a lot about this error none seem to really match my problem. Using my data connection I suddenly am unable to access a site I was using every day. Its not social media and its through the browser. It the ONLY website ive run into where I have this problem and its been going on for a month now. Ive cleared my cookies and cached info. Im using the standard browser on my samsung galaxy 3s. What the hell can I do to access one of my favorite sites again?? It doesnt work no matter if im using my data connection or wifi.
