Your Apache is not running, so it is not surprising you cannot connect.

According to your logs, there is a problem with your logfiles and/or log directory.

Check if your log directory /private/var/log/apache2 excists, and if there is a error_log and access_log.

If there are, probably the permissions are incorrect. Most likely, the directory and/or logfiles are owned by root, and the Apache server is starting under user www. If the directory ownership is not www (ls -la to check), then do a "chown -R www:www /private/var/log/apache2" and try to start apache again.
