pymatgen.ext.matproj.MPRestError: REST query returned with error status code 403.Content: b'error code: 1020'

@tschaume

Dear all,

I am having a similar error. I am teaching a summer school (icmed.engin.umich.edu), and we are using Nanohub Jupyter notebook to query the (legacy) Materials Project. I am teaching how to write large queries, so last week we had ~30 students perform a query that pulled ~7500 materials at a time.

Anyway, the query worked last week, and this week the same code no longer working. I anticipate that we may have gotten blocked similarly to this post here. I have created a separate thread here: MPRester was working last Thursday, now not working, but just found this thread which is similar in nature.

Can you help us investigate and unblock? The summer school Python notebook is attached here for your reference. I also cannot run MP queries from my local computer using this Jupyter notebook on my local computer, which is also problematic.

Best,
Wenhao Sun
