Solution

Today after restoring my snapshot to one of my Alibaba Cloud ECS instance; I was unable to access my website from my browser. I tried a lot of this and that but all in vain. Then finally, after much research, I read that the connection was getting refused by my Web Server, in my case the Apache Web Server.

Once I restarted, the Web Server, the website was accessible now.

Command to restart the Apache Web Server:

For Ubuntu:

 sudo service apache2 restart  

For RHEL/CentOS 7:

 systemctl restart httpd
