Clear Chrome DNS and Disk Cache

I bind a custom domain to the github pages and then remove it. However, when I visit, it always redirects to which is unavailable. I suspect the issue is caused by cache.

First, try to clear/flush the Chrome DNS cache . Just go to chrome://net-internals/#dns and press Clear host cache:

However, when I access, it still 301 redirects to

If I access by Edge/IE/curl, everything works fine. Visit is also fine. So the issue is caused by Chrome.

Use Chrome F12 to debug:

It clearly shows that the website is loaded from disk cache.

Right-click the item and press Clear browser cache, done!
