We have a sub sub domain for our business: https://xxxx.yyyy.datasn.io/
If you go there you will have this error: ERR_SSL_VERSION_OR_CIPHER_MISMATCH
SSL/TLS encryption mode for datasn.io is Full and active.
However if we use DNS only instead of Proxied for xxxx.yyyy, it’s working properly.
What are we doing wrong here? Doesn’t CloudFlare support sub-sub-domains?
