Perfect ! Thank you !!

Shouldn't I just be able to go to mysiteaddress:4201 and the studio should come up?

yes, but it depends, if you try to access the server from another machine different than the server using the mysiteaddress:4201 then the problem can be somewhere else and related to dns or ip resolution, have you tried opening the page in the same server with localhost:4201 or 127.0.0.1:4201? if that works but mysiteaddress:4201 not then it means that you have something not configured right in your network level.

Thanks for all those precious informations! I'll try to see what I can do from the documentation you provided, and if I cannot achieve this myself then maybe drop you a mail as you suggested!

Again thank you very much for your help, if I do manage to do what I want maybe I coud share it with the jsreport team if this become a need for other people than us in the future! :)
