my website was approved by Adsense .
and it warns me that I should Fix ads.txt issues in AdSense
and then I followed steps below:
our web browser. If you can see the file in your web browser, it's likely that AdSense will successfully find it.
`Create an ads.txt file for your site
AdSense provides a personalized ads.txt file that you can download from your account. The personalized ads.txt file includes your publisher ID. Your publisher ID must be included and formatted correctly for your ads.txt file to be verified.
Sign in to your AdSense account.
If there's an alert on your homepage, click Fix now. Otherwise, click Sites.
Click the Down arrow Down Arrow to open the "Create an ads.txt file for..." message.
Click Download. Your ads.txt file is automatically downloaded.
(Optional) If you’re using another ad network, remember to add that network to your ads.txt file. Contact your ad network for their ads.txt information.
Upload your ads.txt file to the root directory of your site. The root directory of a site is the directory or folder following the top level domain (example.com/ads.txt).
To verify that you published your file correctly, check that you successfully see your file's content when you access the ads.txt URL (https://example.com/ads.txt) in y
but it doesn't work.
