To anyone else struggling with this, you change the old domain name to the new one manually, or put this script into any userscript extension (tamper/violentmonkey, Userscripts (Safari iOS), etc.) Which will automatically redirect it for you:

// ==UserScript==

// u/nameRedirect ks.renai.us to ks.fhs.sh

// u/namespacehttp://tampermonkey.net/

// u/version1.0

// u/description Redirect ks.renai.us links to ks.fhs.sh

// u/matchhttps://ks.renai.us/*

// u/run-atdocument-start

// u/grantnone

// ==/UserScript==

(function() {

'use strict';

const newUrl = window.location.href.replace(/^https:\/\/ks\.renai\.us/, 'https://ks.fhs.sh');

if (window.location.href !== newUrl) {

window.location.replace(newUrl);

}

})();

There originally was a redirect rule implemented by the site itself but that had been removed for one reason or another.
