Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:
The subdomain above is reverse proxy through Cloudflare and has Cloudflare’s own SSL setup on it. I have certificate transparency report setup to monitor said domain and I’ve receive report that a certificate is issued for the above subdomain under let’s encrypt, which is not expected.
In other words, as far as I’m aware I’m not using let’s encrypt, just Cloudflare SSL, but a let’s encrypt cert was issued for my subdomain. Is there somewhere I can report this, check why and how the LE cert is issued, or ask for the cert to be revoked? Or is this not a concern for me?
I don’t have much experience handling TLS directly so would appreciate some advice here.
