Jupyter: embed_notebook creates blank html

I have been using embed_notebook to integrate plotly graphs into my Jupyter notebooks. Unfortunately, as of this week, when I use the embed_notebook command, it just generates a blank square. I haven’t made any changes to my environment, so I don’t know what could have caused this problem to occur. It also seems specific to chrome, since I am still able to see my plotly graphs inside of safari and firefox. I would appreciate any insights that anyone can give me.
