GitHub Codespaces not functioning properly (I think its my schools firewall)

[Gangoosterv2]

Describe the bug

Its a GitHub code spaces bug where I think the school firewall is blocking GitHub codespaces. For everyone in my school Github Codespaces says "Oh no, it looks like you are offline! Make sure you are connected to the internet and try again. If you verified that your connection is fine, your firewall might be blocking the connection. Please refer to the troubleshooting guide to diagnose the issue"

Expected behavior
I expected for GitHub Codespaces to normally load like it always does, but this time it loaded but in the middle it always keeps saying the same error.

Screenshots

Device Information (please complete the following information):

• Device: Normal School Chromebook, Intel
• OS:ChromeOS
• Browser: Just Chrome

Additional context
Where it says "Network Error" on the bottom left corner, I did have my wifi on. I also tried clicking "Retry connecting to the Codespaces" but it still didn't work and the same page popped up again.
If possible I hope you can find another way for me to deploy the proxy instead of Codespaces. Thank You!
