Hi Min,
In fact, that's correct!
Webinoly still doesn't support HTTPS in "tools-port" (22222) and actually this is a new feature that will be released on the next major update (v1.7.0) scheduled for december.
Now, if you want to use SSL you have to manually add it to the 22222.conf nginx file.
If not, use the IP to access, http://123.34.12.23:22222
Regards.
