Hey there,
I am really sorry for the delay of this reply as it is a public holidays for us here.
It seems like I was unable to access your site, you can check at my attached screenshot below.
Is it possible for you to temporary disable this IP restriction? Because my current IP address is not fixed.
By the way, may i know do you have try download the launcher installer from
https://stackideas.com/dashboard then upload through your site backend installer page and proceed that installation?
