website not loading or opening

I cannot figure it out, whenever I type in grok.com it tells me there is an error, url is wrong, connection not secure and the website cannot be loaded. No other website ive been on has been blocked like this, and Ive used grok for weeks on the computer. I tried proxy and it still wouldnt work. Websites I know are blocked on my wifi STILL WORK, and there is no reason grok wouldve been banned. Anyone else having this issue, or have a way to fix it?
