Well This is truly A Problem. I wish you would not have pushed that first button.

Excuse me while I work this out...

Okay I checked the HTTP status. I reconfigured the server errors 400, 401, 403 and 404. I double checked the coding structure for SyntaxError.

Eureka: I got it! How could I overlook error 504 Gateway Timeout. Maybe I am human?!?!

OKAY I know I said this before, BUT............... Push that button now.
