IPS Connect Cross Login problem.

[Tres]

I'm trying to use IPS Connect to make the user login to IPS from external app.

Login shows correct response when I put right informations in the form,

but when I check the website it is not logged in.

So I tried cross login, but it did not work.

 

I used cURL functions to send Http Requests.

When I try to cross login, the response is :

"  There was an error processing your login request at one of the sites in our network. "

 

How can I deal with this..?

any idea/?
