Look at your screenshot. The site you tried to access was www.legacykline.com. You did not try
which worked for me on a Chrome derivative browser called Vivaldi. In fact, when I clicked on the link you tried to use, my browser automatically took me to the new address. Your issue is probably a browser security issue involving the DNS server utilized.
I suspect you have a cashed copy, that link doesn't work. For the URL http://www.legacykline.com/, I get this. This indicates they're probably having a web server issue, but they exist.
Given that their database is likely scrambled, your extended URL doesn't find anything at the server address. You're just trying to reference the actual catalog, until the site is up, that won't work.
A check on WHOIS sees that the domain is still registered.
