Why can’t I connect to the Safari server?

Hi fanny89,

Welcome to the Apple Community, where some of us do our best to help each other troubleshoot.

It seems usually one only sees the "can not connect to the server" error message when the web-address is incorrect.

However, there is another discussion thread that contains links to useful articles that may be helpful:

Hope this helps you :)
