That link works, check your internet connection please.
Here's another link where you can read the license: https://ko-fi.com/post/License-I2I4E5325
Now this link works, but it would hurt to say that it is CC BY-NC 4.0
It's not exactly CC BY-NC 4.0 though. There are supplemental permissions and terms to it. So you have to see the whole page to understand what the license terms.
