OK, I’m sure this is dumb, but pulling my hair out … :-(. I’m running an Apache server, and just changed my LetsEncrypt certificates (crt and key) over the the CloudFlare generated Origin Certificate. But, some problems,
- With the RSA certificate, I get " Your connection is not private" in Chrome.
- With the ECDSA certificate (tried both!), I get “ERR_SSL_VERSION_OR_CIPHER_MISMATCH”
