A few weeks ago I had the same thing. But after 30-45 minutes the site has started working again.
Currently, I cannot connect to your site. The best solution is to contact the support.

Is this your site recognized on cutestat.
https://camillinoisnews.com.cutestat.com/

I've checked it and I've also checked two other WA websites.
Only yours is not working.

Since it's not working on my PC as well, I can conclude that the problem is neither with you PC nor your internet connection; although the error message request you to check connection, proxy and firewall.

So you have to contact support.
Let us know the outcome.

If you're hosting here it's best to give support a buzz and if you're not hosting here then contact your host.

I'll check it and revert back to you.
