I followed all the steps on the documentation. I am using cloudflare certificate, but I am getting the error “transport: authentication handshake failed: can’t find certificate matching SHA256 fingerprint” ![image](https://global.discourse-cdn.com/free1/uploads/kopia/original/2X/2/2ee7c35bc23e33fb0ab0cecbc3169309c529d1f5.png) ---

I think this error code is self explanatory… you provided fingerprint that does not match server certificate. ---

I know what it says. But the fingerprint it´s correct, I followed the instructions of custom TLS certificate [Repository Server | Kopia](https://kopia.io/docs/repository-server/) (getting the SHA256 of the certificate)
