Browser compatibility is most likely the problem, Nick. The cluster page uses the built-in Array.includes() method, which appears unsupported <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/includes#Browser_compatibility> in your browsers. It is certainly possible to patch a custom build of NiFi with a polyfill library. But I'm not sure this is the only compatibility issue you will run into.
