[SOLVED] Ads.txt problem for blogger or blogspot in Custom Domain

Recently Google Adsense issued a new policy, one of which is by asking us to make changes or install the ads.txt file on our blog or website in the root folder so that Google robots can access and verify the ads.txt file directly via the address For normal websites, I don't think it's a significant problem. Because all we have to do is put the ads.txt file that can be obtained from our Adsense dashboard page into the hosting where our website is located.

But for users of the blogger or blogspot platform where they wrap their blogger or blogspot address with a custom domain, the above problem will be a little difficult. Here I want to share my experience when I encountered a problem like the image below, and what I did to overcome the error / warning message on the Google Adsense dashboard about fix now ads.txt.
