Trying to Access ERP after installation but I'm failing

I managed to install ERP version 14 on vps cloud, and now I’m trying to access the application using pc but I’m wailing, and there is an issue of making sure that IP of the server and my domain is linked, how can I solve this issue, need help

Hi,

It may help to describe what instructions were followed to install and how the vps firewall has been configured.

Thanks
