Qlik Web Connector Issue

[Rehan]

I am using QLikview Server V12.3 (Nov 2018) and installed QlikWeb Connectors on the Dev server. I am able to access the Web ConnectorPortal from localhost:5555/web but it doesnt work from outside the server . I tried using 

ABCdomain.com:5555/Web it doesnt work. I do have the Allow Remote access to "true" in the Deploy.config .

What am I missing here

Hi,

Is there any proxy that you are using or any firewall that might be in the middle between other machines and the server?

Cheers!
