Problem: My GitHub Pages use Hexo to deploy a website, but somehow ads.txt failed to upload.
I also don’t know why 😂. There may have some issues with Hexo setting.
Solution: Go to Github Pages repo, upload manually. (or upload it using Git) Then wait for Google AdSense detect your file.
Problem: Before the restart, everything works fine on all websites and apache.
Solution: Try below solution, something must be re-enabled if you choose AWS or other web service provider
iptables -A INPUT -p tcp --dport 80 -j ACCEPT
systemctl stop firewalld
First edit /etc/selinux/config, then replace SELINUX= to SELINUX=disabled
sudo nano /etc/selinux/config SELINUX=disabled
Then restart
reboot -h now
