To Reproduce Steps to reproduce the behavior:

1. Go to https://nbviewer.jupyter.org/
2. Enter Jupyter Notebook location https://github.com/quantum-kittens/quantum-computing-basics/blob/master/Qiskit_Reference_Guides/Playing_with_Quantum_Circuits_in_Qiskit.ipynb
3. Click Go!
4. See error

Thank you!

Hey! I see your notebook is corrected displayed now on nbviewer!

Do you recall how much time it took to work? I'm experiencing the same issue here on

https://nbviewer.jupyter.org/github/joao-aguilera-c/CVM-FUNDS-DATA-EXTRACTOR/blob/main/ETL%20de%20dados%20de%20Fundos%20de%20Investimentos%20Brasileiros.ipynb

I get the same error with https://nbviewer.jupyter.org/github/HDembinski/essays/blob/master/Uncertainty%20of%20efficiency%20computed%20from%20fitted%20yields.ipynb

which should render this notebook https://github.com/HDembinski/essays/blob/master/Uncertainty%20of%20efficiency%20computed%20from%20fitted%20yields.ipynb

Initially, I assumed it is because of the spaces in the URL, but other URLs with spaces work fine.

It is happening again. In both cases it was when I changed the file. After one day or two it gets normal. But this sucks...

this is the notebook nb is not rendering..

https://nbviewer.org/github/qutip/qutip-notebooks/blob/master/examples/single-photon-interference-example.ipynb is also not rendering. :/
