Admin page login and Http Error

Can someone please help me out?
I am unable to log on to my blog because it keeps on saying that safari cant open the page. However, when i go on to my blog, it is working fine and can be seen by others.

Also when ever i tried to upload images, i got a HTTP Error. How do i fix that?

This is so frustrating!
