Google’s Chrome browser keeps its own DNS cache for whatever reason. Clearing your local OS DNS cache isn’t good enough to resolve a new IP that it likes.
Rarely do I ever run into this issue on my Windows 7/8/10 machines but for Mac users it’s a more common issue.
But here’s what I found worked for a sticky DNS issue I just ran into on Windows 10:
- Clear OS DNS cache using “ipconfig /flushdns” in the command prompt.
- Go to “chrome://net-internals/#dns” in Google Chrome
- Click the “Clear Host Cache” button on the page that is now displayed.
- Clear OS DNS cache using “ipconfig /flushdns” in the command prompt.
