Trouble opening my Codespace in both Microsoft Edge and Google Chrome

Hello GitHub Support,

I’m having trouble opening my Codespace in both Microsoft Edge and Google Chrome. It gets stuck during loading and shows errors related to Content Security Policy (CSP), refusing to connect to certain URLs like main.vscode-cdn.net.

I’ve tried:

Using incognito mode

Clearing cache

Switching browsers

Restarting the Codespace manually

But nothing works — it still fails to load.

Could you please advise if this is a known issue or if there’s a workaround?

Thank you,
Abdi

This issue may happen if your browser or network blocks VS Code CDN resources.
I try these steps and solve problem:
Disable any browser extensions or ad blockers.
Check if your firewall or proxy blocks the domain vscode-cdn.net.
Try using another internet connection ,for example, mobile hotspot.
If the problem continues, please share a screenshot of the error message.
