Sv_loadingurl page preconditions to create a loading page

[kelvynnjs]

Hello folks, i' m sorry for disturbing you,
i used to have a Webnode formatted website for my server (of course,it expires,) so i got a dedicated host,i'm trying to make it work as my loadingurl but the site just appears as a blank page
do you know what changes do i need to make,or something to know about before creating a page that actually loads in the server
(all the other sites work,except this one)

this is the website
https://omniserversbrasil.com.br/wp/

I investigated a bit with Fiddler. Your website is refusing Awesomium connections.
This is what a request from Chrome looks like:

As you can see, Awesomium is proposing SSL3.0 instead of TLS and it has no modern cyphers such as ECDHE. I am no expert, but I think this might be why the connection is closed. It might also be refusing weird User-Agents, but that would be surprising.

Thank you for the heads up ! appreciate the help, @MrManiak
