welcome mowogo

i'm sorry for your problem, but as the "self test", lots of people here, and myself report, your HFS is working perfectly all over the internet.
i'm downloading your mp3 right now.
the problem seems to be related only to those around you. funny.
as maverick noted, that message you got doesn't seem to be the standard message, so i guess that if you find who's giving you that message, you will find the offender.

anyway, if you already tried to type the full form
http://97.80.169.177/then my suggestion to work around your problem is to not use your numerical address, but a name (domain).
you can get one for free at no-ip.com and dyndns.com
you just have to register there.
