I am receiving a 403 Forbidden Error on the Nab?z App.

Hello everyone, first of all, best of luck to all. I have a technology blog called Techno Agency, and recently, the Nab?z APP application was added to it. However, as you can see from the image below, I am encountering a 403 Forbidden error when the application directly pulls news from my website. I have tried all possible methods but still can't find a solution. I am at my wit's end. Could you please help me with this issue? I have contacted the application developers, and they say the issue is on your end. I have also contacted my hosting company, and they say they can't do anything about it. I asked for help from someone on Bionluk, paid them, they did a few things, and now they are not responding. Can someone lend me a hand? [Link to image: https://hizliresim.com/s0e8xb]
