Cloudflare SSL not working - NET::ERR_CERT_AUTHORITY_INVALID

I added the domain on which the self-signed certificate is installed, Cloudflare determined the Full mode itself, but half a day has passed and https shows me an unsecured connection with an invalid self-signed certificate - NET::ERR_CERT_AUTHORITY_INVALID

when will Cloudflare start?

all sorts of testers show that Cloudflare SSL is CORRECTLY installed on the domain and sait is available via HTTPS)))

Please stop opening duplicate topics, and address your issue in Cloudflare's Origin Certificates are not valid certificates.
