{error: {code: 498, message: "Token Invalid.", ...}

HI, 

I am currently using ArcGIS Enterprise 11.4 (Portal-Federated Server) with a developer account subscription. When generating a simple basic API key, I repeatedly encounter a white screen. Checking the network reveals error 498. I have attempted this in different environments, yet the issue persists. Although my environment is secured, I am facing this problem on my local machine (Secured Environment) where the portal is installed. Each time, the key appears as an invalid token.

{
"error": {
"code": 498,
"message": "Token Invalid.",
"details": [
"The required authentication information is invalid. The token is either invalid or has expired."
],

So that means not even a pre-setup API Key perhaps stored in an environment variable is a no go?

(As opposed to passing it as a token in a url, since EXB does not yet honor a lot of the url parameters that WebAppBuilder might have?)
