I'm a newbie about security issues.

I had this terrible error while I was trying to recharge my mobile on-line:

Tunnel or SSL Forbidden
Description: 9000 is not an allowed port for Tunnel or SSL connections

[ using the right button on the window, this address appeared in the "properties" filed:

That is very very strange because I have done charge operations many time during past months.

I don't know if this is an error generates by the server or by my PC. I noticed this strange error after an DSL modem installation on my PC. I know anything about this problem...
so please help me.
Is my modem the cause or is it the server ?
