When I navigate to https://privacytests.org/me.html and click the button, the new tab displays:

error: {
  "message": "TypeError: Failed to fetch",
  "stack": "TypeError: Failed to fetch\n    at https://test-pages.privacytests2.org/supercookies.html?mode=read&thirdparty=same&sessionId=7141134940038344&me=true:52:32\n    at https://test-pages.privacytests2.org/supercookies.html?mode=read&thirdparty=same&sessionId=7141134940038344&me=true:72:7"
}

and the original tab shows the following 502 error:

I've tried this in multiple browsers with the same error.
