Hi sorry about this issue, i'm run out of ideas of how to access my deployed project on our main domain server.
By following the Guidelines provided in the GitHub I installed properly the keter, put the .keter file in the /opt/keter/incoming path but once i access it on the browser it always see the nginx page.
Also I use fpcomplete IDE for my project and I just download the file executable file there.
Thank in advance
I've solve this by following the instruction given to me on Github
