I am an app developer and one of our customer's says that they are not able to use our app likely because of their web content whitelist settings perhaps missing a url. When I investigated, I found that the only url that could possibly be missing is localhost.
I was wondering if you need to specifically whitelist localhost and if so, if you also need to specify a port.
Also how exactly should I write this in the whitelist.
Ie- should it be localhost or localhost:8080 etc or http://localhost etc
