You need to check that the browser is implementing the final RFC 8446 version and not an earlier draft version -- two are incompatible by design (and OpenSSL 1.1.1 implements the final RFC 8446 version). IIUC, only Firefox nightly as of approximately today will support the final RFC 8446 version; I haven't looked into Chrome yet. -Ben -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
