I didnt mention this before and not sure if its related
I originally signed up to this site which i found on Google.
The link it gave me was http:///www.techist.com/
The 2nd day I tried logging in I got the "could not connect" error.
(And sometimes will get that error and sometimes not)
Later on I found out that http://www.tech-heaven.com/forum/
was a link to the same site.
So in this case it was a redirection???
Maybe related to your problem...
