Verifying Site Domain | Google Console

Having a similar issue to this thread, which has now been closed. When trying to verify my domain (a bubble.is domain), I continue to receive the below error message.

Could not find the verification file in the required location

I have been unsuccessful after trying the following steps:

–Adding the HTML tag to the header
–Uploading the HTML file to the root directory section

Any direction would be greatly appreciated!

@danidonch There is typically a lag for Google to recognize yourdomain.com/filename once you upload file to root directory > push to live > update Google Developers Console.
