Hello, we have been using KoolReport ChromeHeadless PDF export without issue for over a year now. All of a sudden today, we are receiving an error message: "Request Failed:" No changes were made to our codebase.

Looking at a previous reported issue like this (https://www.koolreport.com/forum/topics/2066), I hit the following URL to test: https://service.chromeheadless.io/api/export and received the following response:

{
  "error": "Failed credential!"
}

According to that post, this is a "successful" response from the service, but we're still unable to export from our application. Please advise ASAP, thank you!
