on the computer where you have installed Qlik Sense, that computer should have a public IP. Once you have that then you can access is by:https://xxx.xxx.xxx.xxx/hub/
depending on if you are using http or https the above address will change.
if you would like to use https then you will need to buy a certificate and install it otherwise you will get certificate error but Hub will still function properly.
the first step is to make your computer internet facing(having a public IP).
if you don't have a certificate then that's okay as long as you are not expose. You can always use Http only.
if you have public IP then you can use that IP address to access your hub.
for example if your IP address is 22.214.171.124 you can access your hub using the following link:
as long as your are not mapping your internal ports the above link should work fine.
thanks for your answer ! now,I tell you my situation.
this is my sense hub port picture:
my public IP resolution domain name is hub.ecota.com.cn. When i access my hub with the domain name,it would jump to validation port.
but it can not access the Authentication port. I want to know how to skip the validation jump.
