LiveStream Websocket problems

I am following this tutorial:
https://docs.omniverse.nvidia.com/prod_extensions/prod_extensions/ext_livestream-websocket.html

When I follow the video, I can access my Create project on my Chrome browser by using the standard: http://localhost:8111/streaming/client

But when I try to use this on another computer, I get this error:

I have followed the tutorial and made the URL to be like:

http://91.153.83.137:8111/streaming/client

Also this gives the same error:
http://91.153.83.137:8111/streaming/client

So, what can I do?

Yours,

Nice!
With the help of GraphicationMaker at OV Discord, I got this solved.

I changed my workstations IP to a static one. I opened port 8111.
Now all works as it is supposed to be.
