Ports: 80,443/tcp Please note that I can use curl, and get html content. $ curl [http://www.zethago.tk](http://www.zethago.tk) Please also note that I am currently experiment this apache server on my laptop, which I would turn it off sometime.

http is port 80 the error / issue is regarding https ( port 443). using curl I can access [http://www.zethago.tk](http://www.zethago.tk) but not [https://www.zethago.tk](https://www.zethago.tk). Can you access https (port 443 ) ? ---

I have not set up any https. I keep thinking that I need to create certificate, first. I will try what you suggested now by going to the dns, and adding https. Thank you. ---
