My one click install wordpress site cannot load from other devices.

Hi I have created a one-click install wp droplet and installed wordpress successfully. I have done everything according to DO docs. After installed theme I tried to check the website on other computer and mobile devices and it gives the ERR_CONNECTION_TIMED_OUT error. The website is working fine on my computer only, I am able to login and edit the website with no problem. The only thing that I have modified is the php.ini file, which is required to install the theme and import the theme’s demo. This is my first time doing this and I literally have no idea what is going on and what else to do, I have search everywhere I could and still haven’t found the solution. Please advice on how to fix this problem. This is my website https://buytickets.my
