Services 3.5 q=system/connect.json 404 (Not Found) I have code that use JQuery to call services module and login.
After Login, I call token through ?q=services/session/token and gets the token of the user.
I think that i have got the right token...
After that the code calle to ?q=my_services_endpoint/system/connect.json and pass through the header the token.

the problem is that i get those lines in the console and no success of course...

what version of drupal did you use?Can you try to remove the q?= and try it again?Also i notice on OPTIONS http://{localhost}:8888/drupal2/?q=system/connect.json 404,it doesn't contain your endpoint.
