Hello, I’m experiencing a problem with GitHub Pages that appears to match what other users have reported in recent community discussions.

My site was working normally, and I did not change anything in the repository settings, code, or GitHub Pages configuration. However, the site suddenly stopped rendering.

Important details:

The page does not return 404 — it loads with status 200, but the screen is completely blank.

The repository, branch, and GitHub Pages settings are all correct and unchanged.

The site was working earlier, and then stopped working without any commits, config changes, or domain changes.

Other users in similar discussions reported the same behavior, but no clear cause or solution was identified.

This issue seems to be happening on GitHub Pages itself, since nothing in my repository changed and the site had been stable for a long time.

Could someone please help investigate what might be causing a GitHub Pages site to suddenly stop rendering without returning any error like 404, and without any modification from the repository owner?

Hello, technicaly there are something wrong, if all is correct your page will works correctly. Try to fetch the code, or the github settings, and you can use github copilot to help you to solve your issue. Happy coding!

I identified the issue. I was using the following CDN URL:

https://cdn.jsdelivr.net/npm/redoc@next/bundles/redoc.standalone.js

This endpoint is currently returning 404, which caused Redoc to fail loading.

I replaced it with a fixed version:

https://cdn.jsdelivr.net/npm/redoc@2.5.2/bundles/redoc.standalone.js

After updating the script reference, everything started working correctly again.

Thanks for the help!
