@Krydos I didn't know that. I have been re-reading your messages and cannot find any mention of this anywhere :
I did find this though :
And I also did say :
I said it was good enough, I Didn't insist on you to waste your time.
The FAQ did say to open a customer ticket for this specific NGINX request, I didn't know I was supposed to understand everything at first try.
I also mentionned I was very new to all of this, my first line of code was 1 month ago, sorry for not understanding node.js, ports and websockets right away.
Also, it does work in the main citadel.helio.st domain, the files just need to be in 2 different folders, i'm sure there is a better way to do this, that is why I asked.
Thank you for your help, won't take up more of your time
