Pygame and Python-CMUGraphics not working for students on chromebooks

Bug description:
Hello, I teach computer programming at a high school. Right now, we mostly use the Carnegie Mellon University (CMU) IDE for coding in Python. However, it is limited and I would like for my students to access to other cool things like Pygame and Kaboom. Unfortunately, when my students use their district issued chromebooks on the school internet, they cannot get Pygame to work. Also, you do offer a Python-CMUGraphics template and that works fine for me on my home computer, but does not work for my students on their chromebooks (and I just determined that it doesn’t work for me on my Windows based teacher computer either). The same is true for the Pygame template. I have included screenshots of both results below.

I have schedule a meeting with my district tech folks for next Tues (Oct 24th) where I am going to ask them to work with me to get this working. However, I could use some help from you. For my students, they can run on their chromebooks, but they can’t run programs with the Python-CMUGraphics template or the Pygame template.

If you can think of any reason why that is, I would appreciate your input. For example, it appears that is not blocked by our firewall, but perhaps there are additional domains that need to be whitelisted?

Expected vs Current Behavior:

Steps to reproduce:

Bug appears at this link:

Screenshot(s)/Screen Recording:

Browser/OS/Device: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/ Safari/537.36

Replit Profile:

The domain is probably blocked. This domain is used for the output tab, graphical output. Many schools block it because replit can be used to create proxies.
A solution is to only use Repls can’t access the internet, and many community features are disabled, but graphics work.

Edit: is now having problems with output too. See:


Thank you for your reply. I had my student try and I was so hopeful, but it didn’t work with either Pygame or Python-CMUGraphics. I will ask my district tech folks about whitelisting
