Website only opens in Safari and not other browsers
I've been working on this customer's website for years (deborahking.***). A couple of days ago, I suddenly started seeing "It works" or This site can’t be reacheddeborahking.com refused to connect. Try: Checking the connection Checking the proxy and the firewall ERR_CONNECTION_REFUSED in Chrome, DuckDuckGo, and Firefox, but I can reach the site in Safari. I've followed all the online troubleshooting suggestions (to list a few: cleared cache, reset settings, uninstalled & reinstalled browsers, cleared DNS, turned off firewall, verified IP not blocked on website server, reboot computer, connected to a different WiFi, reinstalled Mac OS, fixed disk, etc). I have colleagues, one on Mac & other on Windows, and they see the site in all browsers. So, all my troubleshooting has isolated it to my Mac, but I'm unable to identify what is blocking all but the Safari browser.
