new sever installation, can't access Studio/HTML Designer

[hopper08]

Newbie here.
While I was away from work a then-coworker set up jsreport on our Dev machine. I'm now trying to mimick that installation on our Prod machine, but she left no notes on what she did during her installation.
I installed in on Prod, which I think I've done successfully. When I start it up, I see a bunch of text that looks promising, the end of which says: (I've customized it to used port 4201)

2018-05-10T18:56:13.510Z - info: jsreport server successfully started on http port: 4201

2018-05-10T18:56:15.126Z - info: reporter initialized

But when I go to the Studio/HTML Designer to see my templates, I can't access it. I just get a "This site can’t be reached" message.
Shouldn't I just be able to go to mysiteaddress:4201 and the studio should come up?

Is there something else I need to do or should be aware of?

Thanks in advance!

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.
