When I'm trying to connect my ClickHouse instance on Alibaba Cloud with https protocol from my Mac, and this is the response error:

Failed to connect to cc-xxxx.germany.ads.aliyuncs.com port 8443: Operation timed out enter image description here

curl --cacert ./Downloads/ClickHouse-CA-Chain.pem https://cc-clickhouseinstance.connection.string.ads.aliyuncs.com:8443/ping

I have tried ping, and it shows ok, so what the problem would be?
