Hello. I have a problem with a certificate signed by Global Sign. I put the status in the settings of Cloudflare (Full Strict). My website progres.store not working. Prompt decision. Thank you.
I’d start by turning off Cloudflare (use Grey Cloud in DNS) to see what certificate your site is using.
If your site works properly on its own, then you’re ready for Full Strict.
You might even try going regular Full as a temporary fix.
Personally, I use the Origin Certificate from the Crypto Page that Cloudflare can generate for my site. It’s free and lets me use Full Strict. Before that, I used Let’s Encrypt and that was very good.
