Website giving warnings with www

Suddenly, one of my forum websites won't load and is giving security warnings - this is in Firefox incognito mode (below). And all other browsers are similar. It will load if I use https only but not with https://www

Contacted server and they are talking about changing CNAME in dns records. But why is that needed - it's been perfectly ok for the past year or more so why does DNS need changing?

DNS is on Cloudflare - checked cname and it had a flag recommending to set it to proxied to avoid IP address being revealed. So I did that and it's made no difference. Is it possible it's some kind of attack? The site still loads with https only.

Sorted now. I guess the proxied cname took time to filter through. Still no idea why the warning said my SSL certificate had probably expired.

Ok I think I worked it out. Cloudflare only automatically renews SSL if the cname is proxied. It wasn't proxied so the SSL expired. It's proxied now.

Even though Cloudflare provides SSL, you should install a certificate on the server so there's full SSL between the server and Cloudflare. Cloudflare has certificates you can create in their interface for long spans of time (10+ years) that you download to place on your server.

You can actually just use a self signed one, if you choose the Flexible SSL option on CloudFlare.
