Error loading notebook

The notebook does not load. It gives error:
405: Method Not Allowed
OR
Error Loading Notebook
Forbidden

I’m getting this error in all notebooks

This is definitely unexpected. Can you please provide a screenshot including the URL to see if we can understand/reproduce the problem?

What browser are you using?

Microsoft Edge, but that shouldn’t be the issue as it was working fine yesterday.

Maybe @brospars will have a better idea on what could possibly be the problem.

405 Method not allowed means the LTI protocol is blocked by your browser. This is probably related to third-party cookies being blocked for cloud-mooc.inria.fr. Can you try disabling adblocking plugins ?
