Unable to connect to code spaces for this course

[mkgsmith]

Hello,

I am unable to connect to the codespaces to complete setup and I keep getting an error message “Oh no, it looks like you’re offline!” message despite trying the following troubleshooting and disabling my VPN. My machine is connected to the internet and starts the "setting up your codespace message in the lower right but continues to fail.

I'm using the latest version of Firefox and perhaps Codespace client can’t reach the Codespaces backend. A few things I have already checked:

Network connectivity – Ensure your internet connection is stable and no firewall or VPN is blocking *.github.dev or Codespaces endpoints.
Browser caching – Try clearing cache or opening Codespaces in an incognito/private window.
Browser compatibility – Make sure you’re using a supported browser (Chrome, Edge, or Firefox latest versions).
Sign-in session – Log out of GitHub and log back in, sometimes stale tokens cause API failures.
Restart Codespace – From GitHub → Codespaces, stop and start the Codespace again.
