are you going these sites at work? if yes, ur IT dept might block everyone from acessing these websites....
if it is ur computer at home, u might have set the cookies to block accessing those websites or u used some firewall software like zonealarm, norton internet security, etc...

Alanchia03, we can come up with a lot of reasons for this behaviour, but the right reason? Well only after we ask a few questions.
I'm assuming you're trying this from work?
If so: Your work may be using a proxy server. The proxy server probably has in place filters that restrict access to various websites. Your browser is configured to use this proxy server, and so you are subject to those filters.
When using Telnet, it is doubtful that your workplace uses the same proxy server, and accompanying filters, to restrict access to Internet destinations.
Yes it is the same destination IP address, and the same destination port, but your web browser says "I'll let this proxy server handle my request", whereas telnet says "I'll just try to connect and see what happens"
That "see what happens" is the key; most companies just blindly allow telnet to happen without any filtering of any kind. Amazing that they still don't 'get' it.
