Found the problem. It is not because of the SSL, it is because of the IP set for that domain.
From Creator of Hiawatha:
Hugo Leisink
When not specifying an interface in a Binding block, Hiawatha will bind all available interfaces. When a second block has the interface option, that interface is already binded by the previous binding block. To solve this, specify an interface in the first binding block.
In Hiawatha defaults init.conf you don't use the interface option, you bind Hiawatha to all IP's. In my website, I added exclusive IP, and you use interface option in binding it. But, it is already bound to first init.conf binding id port_443.
You have to list all available ip's in the init.conf, using interface option.
This is a critical bug in KloxoMR and adding any exclusive IP to a website will break Hiawatha.
Please fix. Thank you.
