Legacy API key for MPRester not working anymore


I was working with the legacy MPRester API as recently as yesterday and today when I started to work on my project, I am getting a 403 error saying my API key is not valid. Nothing about my Jupyter notebook changed from yesterday to today, so I am not sure what is happening. Moreover, legacy.materialsproject.org seems to time out.

Does anyone know what is going on?
