Error message when trying to open a Report on app.powerbi.com / Reports do not open

[CM000n]

Hi Folks,

from today on (22.02.2016) I get an error message (see picture below) every time  I try to open an report on app.powerbi.com.

It just shows up this error message and the reports do not open anymore.

I already tried to refresh the data via the Poer BI Desktop App, but without any success.

I also already opened a ticket for this issue but I'm interested if anybody else has this problem?
