my *Home-Link* dos not work

Hi, i am just installing my wordpress and when i go to the home-button there is no conection to the internet. The adress is wrong: instead of https:// it is showing: http//. So , i think i have put somewhere the wrong adress. But i do not know where it could be. In the dashbord under general installation the adresses are fine. Maybe there is an other place where something went wrong with the adress. could you give me some help?thanks wolf
