Original GitHub issue: https://github.com/NginxProxyManager/nginx-proxy-manager/issues/2414

I'm using NPM v2.9.18 on my Unraid Server with two domains. Both domains are proxied over Cloudflare. For some reasons it shows "Cloudflare Inc ECC CA-3" as certificate, but on the second domain there is only the "E1 - LetsEncrypt" certificate. Is that a known error? The proxy works fine, if i ping the website i'll get a answer from Cloudflare servers. I tried to reset my API aswel reinstall NPM but nothing really works.

Have you checked DNS locally and on the internet? Seems like you are hitting NPM directly for your second domain.
Perhaps check from external with something like ssllabs this will show if its working as you think in cloudflare and its something on your network that is not going through cloudflare (e.g. host file entry, local dns being different)
