Browsing6853 I am not sure if this is entirely Kagi's fault: !wayback https://google.com/about/ - DuckDuckGo works and Kagi fails. !waybackmachine https://google.com/about/ - both fail the same way (??)
NS2555 I figured out the problem. If you search for "!wayback https://google.com/about/", you will get redirected to a link that is: https://web.archive.org/web/*/https%3A%2F%2Fgoogle.com%2Fabout%2F The link is not correct, however, you can fix the link and make it redirect properly, simply via removing the */ part of the link, which in turn makes it into https://web.archive.org/web/20220217084001/https://www.google.com/about/ , which is a correct link. Same applies to !waybackmachine https://google.com/about/
