Cache or cookie problem

I am using an API Key to authenticate and run queries. But something is wrong with cookies or cache. I have to clear the browser cookies and cache in order for this authentication error to go away.

I am using Google Chrome on Mac.

{
  "data": {},
  "errors": [
    {
      "message": "Unauthorized: authentication required to perform this action!",
      "extensions": {
        "code": "AUTH_ERROR"
      },
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "qualify"
      ]
    }
  ]
}

That’s an error message you are getting from your server - only the people who implemented your server might know why you are getting that in this situation, I’m sorry.
