Does anyone have idea why Cloud UI tool does not open with Exa Operation URL with port 8835? Exa Operation working fine but UI tool does not open at all. Where can we trace error for same?
I have just checked by creating a new AWS cluster and scaling down the EC2 instance type as described with the hands-on exercise 3a in the AWS course.
It works for me as decribed, so I cannot reproduce your problem. Maybe it's a browser issue you encounter and it works with a different browser.
If the issue remains, you may want to take that to the general discussion forum, as that is not (only) a course related issue but more a general problem with our Cloud UI tool.
