I have read the suggested associated articles but they do not seem to answer my problem. I am new to Cloudflare and have just set up my site basically using all the Cloudflare default settings.
I cant access my site at all with any https prefix yet in my control panel under SSL/TLS my site is shown as
Your SSL/TLS encryption mode is Full and the Full option (recommended by cloudflare) is selected. (not Full Strict)
I can change to flexible and immediately use my site via https (I know this is not full ssl).
My question is - Can I use Full, do I have to wait for something to be configured, do I have to Install something on my server. Do I use Full or not, if so how ?
