I cannot listen at work, but at home
If you cannot listen at your office you are probably behind a firewall which blocks certain internet traffic. Our radio (and many more stations around the internet) use dedicated "ports" that many IT department blocks. Mainly for security reasons. So to the technicalities, our servers operate on port 8000 and above. I most cases lower ports remain open.
We have a server running on port 81, you could try this one!
