crossorigin.me is not working

I get a warning like this
```
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://crossorigin.me/https://google.com. (Reason: CORS request did not succeed).
```
when I try to fetch a resource. Can be reproduced by running
```js
fetch('https://crossorigin.me/https://google.com').then(r => console.log(r.ok))
```
