Did you add the furnidata to emulator? External Vars? If all correctly purge cache (Cloudflare) then try again. If its still same problem hit f12 and show me your error logs.
I do have a retro package somewhere. I'll see if it works and give you link.

Sorry my bad, I haven't set this up but this should work. Give me a shout if it doesn't
Basically what jerry says but do remember you have to enable HTML client. Two ways to do this is by some coding php allowing html tags to work, or the way Jerry said.
You forgot to open ports and allow all connection. Clear cache sign out and sign in, If its still 76% Post your emu config, external vars and client.php please.
