Keep getting that when trying to post
5xx(e.g. 500) error codes responsible for some Server-Side issues.
For more details you can google “HTTP errors codes” 
Figured as much, never got a response and googled it but nothing seemed to solve it. I was looking for something more specific for enlisted but I guess in this case it’s a more broad term being used.
Sadly I was hoping I could wait it out but it’s been happening for over a week, and I have done all the recommended things to fix it.
For giggles… its one more than error code 499? Lol have you turned it off and on again? Hope your issue got fixed xxx
