Visdom Webpage Shows Blank Blue Screen

[ghost]

I started the Visdom api on a cloud server, and tried to access it by mapping its port to localhost.

When I open localhost:8097, it's just a blank blue screen. I can unselect/select environment "main," but nothing is different. Other buttons in the page header doesn't produce any difference, either.

The output on the backend:
