Clicking `Subscribers endpoint stats` does nothing – no errors displayed, but also doesn't pass.

Hi,

I'd appreciate your help figuring out why Subscribers endpoint stats could not verify my server. The log on my side shows nothing; I do not even see Fitbit trying to reach my server.

• cURL from anywhere to the same site looks OK – 204, 404 returned for the requested code
  • correct code
    HTTP/1.1 204 No Content
    Server: nginx
    Date: removed
    Content-Type: application/json
    Connection: keep-alive
    Vary: Accept-Encoding
    X-Frame-Options: SAMEORIGIN
    X-Content-Type-Options: nosniff
    X-XSS-Protection: 1; mode=block
  • wrong code
    HTTP/1.1 404 Not Found
    Server: nginx
    Date: removed
    Content-Type: application/json
    Transfer-Encoding: chunked
    Connection: keep-alive
    Vary: Accept-Encoding
    X-Frame-Options: SAMEORIGIN
    X-Content-Type-Options: nosniff
    X-XSS-Protection: 1; mode=block
• Subscriber endpoint stats for the dev server with ngrok verified successfully 
• CID: xxxxxx

Changing to HTTP/2 didn't help either.

I found the reason and fixed it using https://whatsmychaincert.com/ . It was a `Chain issues Incomplete`.

The endpoint was verified successfully after that.

Thank you.
