ironman exactly! Your IP address is not public. You are pointing your website to 192.168.43.43 and that is not a public IP address, therefore you cannot reach your domain name by typing your address into the browser, but locally works without an issue, you need to add your IP address that is public and then you can reach your domain name.

    ironman change the values of your private IP address to your public IP address and you should be fine. You can find what is your public IP in several websites such as this one provided by google.

        how can i change my private ip address into this public ip address ? and you know that public ip address always change then how can access the web if public ip address changes ?
        My public ip address
        103.7.78.163
        Your public IP address

            ironman mmm thats a bit tricky then to have your local machine working as a server since your IP changes all the time, you will have to change the IP everytime it changes if you are using a dynamic IP address and not a static one like most servers. I would suggest a cheap vps machine for you to work on that domain name and then you can have your website running all the time.

              i had a vps server before but now i dont want this . i wanna run my domain on my machine no problem i will keep always on my machine for run website . can you tell me boss how can i change my private ip address to public ip address on centos ?

                ironman You might have to do some reading about it, here is a good guide for you.

                                To access a website over the Internet, HTTP requires port 80 open. In addition to opening the firewall inside the system, the security group of the VPS service provider also needs to open the HTTP traffic, that is, to release port 80 for the firewall.
