problems with JsConnect, unrecognized URI parameters and undesired requests.

So i'm trying to integrate the forums to my own webapp.
I've followed instructions for JsConnect and set it all up.
However few things i've found which is confusing:
1. when i enter the forums as a guest, just going to the dashboard, a request is made to the SSO endpoint at my app with the following:
forumsso?v=2&client_id=1883878595&Target=%2Fdiscussions&callback=jQuery110206107371338415357_1524120535919&_=1524120535920
it is missing any other parameters that the SSO endpoint is expecting no timestamp no sig no nounce, also i don't even understand what's the purpose of this call on each page view.

2. when i click the Sign-In button at the forum it redirects me to my apps login page and when i do, it redirect me to the SSO endpoint page, again with not enough parameters:
   /forumsso?Target=%2Fdiscussions&_=1524120752997&callback=jQuery11020826838299950815_1524120752996&client_id=1883878595&v=2
   what on earth is going on?

I'm using the PHP LIbrary:
