My website has been secure through cloudflare for nearly two years. All of the sudden two weeks ago it loads as unsecure. I cannot seem to fix the problem and I never changed anything two weeks ago. Full strict is enabled. Universal certificate is active. Cqnnot figure out what the problem is. Nameservers are correct. Have been so for nearly two years.
It’s probably Mixed Content. What’s the URL?
Your website is not using the Cloudflare proxy, so the issue is on your server (your ACME client, eg Certbot, isn’t running or correctly set up to auto-renew).
But it looks like that was just taken care of, since now when I load it it shows a LE certificate issued today (not the same one posted above).
