Cannot reach EPM Canvas (localhost:88)


I was testing Canvases on EPM and over a graph I clicked on "Show underlying data" and it started loading. I had already done this before and worked ok. However, this time it just seemed to be stuck so I refreshed and I got a pop-up that says "errorLogin" and when I go to the server and go to localhost it just doesn't reach.

I get the typical page "Internet Explorer cannot display the page".

Any ideas?

Thank you!
