403 Forbidden NGNIX Error on ads.txt

I have uploaded ads.txt on my server via file manager and yet it is showing me ads.txt 403 not found when I go to the URL.
Any solution???

Permission issue. Assign correct user and group for that file.

like this …

chown -R www-data:www-data /var/www/ && chmod -R 755 /var/www

nope yet the same

Check access.log and error.log?
