Yes, it’s connecting to my server showing current content - did some quick changes to be sure and they were updated.

Yes, it’s currently only on full (not strict) because I need the site up today.
I’m really puzzled by this, as this was working perfectly until yesterday and didn’t do any changes on my side. Maybe it’ll fix itself back in a few days or so.
I would probably open an account ticket with Cloudflare (that should not be automatically closed) and explain the situation.
Having a seemingly valid certificate setup but Cloudflare still does not validated the certificate and throws a 526
and also link to the thread here, so that support hopefully does not not immediately provide a canned response but realises that we already looked into it.
Right now, I can only explain this either with some account glitch or something overriding your settings, though you confirmed the request goes to your server and your server has a valid setup as far as I can tell.
Afraid your setup is the one-in-a-million where there really seem to be an issue. At least as far as I can tell, not having access to any debug tools on Cloudflare’s side.

Just to be completely sure, the AAAA records your domain and www both end in 14d?
And you definitely have no Origin Rule in Cloudflare?
Have you tried the good old restart trick (of your web server)?
I’ll be honest, this is a really weird issue.

Yes, they all end like that.
No origin rules either. I’m not able to restar my web server by myself, but I’ll ask the provider.
Thank you everybody for trying to help me out.

Try the restart, though I am not sure it would fix much, as the certificate in general is fine. Unless, the server has some obscure SSL session caching and still presents Cloudflare with any expired certificate. That should be unlikely, but then who knows.
Generally speaking, the thing is a bit odd and only someone with access to Cloudflare’s infrastructure could verify for sure why Cloudflare is not able to validate the certificate.
@leandrocabo93, it seems as if the following might be the reason
While the server generally presents the right certificate, it would seem as if the Cloudflare proxies receive a generic self-signed certificate.
Could you clarify with your host if they have SSL caching or any special configuration for Cloudflare IP addresses in place?
