While this code works flawlessly in local, it doesn't work when I broadcast. When I check the item and look at it, all the necessary code I can see it being called. I thought the problem might be in the database connection, I created a simple sample table and pulled data on the server works smoothly. However, when I register to the database with JsonResult, it does not get into the database almost on the server side. It does not give any errors. Just looking at the item with check item again, I could see that it wrote 404 bad request. Apart from that I have there is nothing.
