Thank you for your comment.
I did clear cache but still same issue.
I did clear Chrome, Firefox, Microsoft Edge, etc. but I can’t access. Even my phone too.
And what yellow banner are you referring?
I tried everything but still same problem.
I did flush DNS, clear cache on every browsers.
I can only access using VPN or my cell phone network.
It’s a mind boggling.
I don’t understand why I can’t access domain using home DSL network.
Thank you for your support.
I really appreciated.
I don’t know if this is gonna work because this might be crazy but can you go to Task Manager and kill every Chrome/Google process then reopen Google Chrome again then clear your cache.
If it doesn’t work then you might wanna check out your website in 10-20 hours.
Most likely, the automatic DNS server address points to the DNS servers provided by your ISP. Those DNS servers may have cached DNS bad records of your domain. Since you don’t own those servers, you can’t clear that cache yourself.
Google’s DNS servers typically cache records for much less time than your ISP’s servers do, which is why it does work with Google DNS, and with a VPN (which should be using the DNS provided by the VPN provider, not your ISP’s DNS), but not with your standard home connection.
The multi level cache in both your computer and at your ISP can be messy, and some providers are just plain stupid with how long they cache DNS results. But this is just how DNS works.
