Https error, secure connection failed



I’m really new to hosting websites and giving them a domain. If I’m honest, I don’t know what I’m doing.
and I have created this site: and have parked the site to but the problem is that there is “no secure page” the browser says.
when I connect the site changes to https://, the browser says that it failed to connect secure and gives me SSL_ERROR_NO_CYPHER_OVERLAP.
I have changed the grey cloud to yellow because I really want to have a secure website and if I have grey cloud on, I will not have the https://.
I have waited before nearly 24 hours but I got really frustrated and changed the grey clouds to yellow and now this happens.

What will I do so I can get https:// working on my domain?
I’m very new to this so all help is needed.
