Problems with proxy’s on my iPhone 14 Pro, IOS 18.1

Hello, I recently tried to connect proxies to my iPhone with the Shadowrocket application and others. None of them worked, and I bought the proxy. Then I tried putting the proxy on the Wi-Fi directly, but it didn't work. The internet just doesn't work. I know it's the iPhone because I've tried Wi-Fi, 4G, 5G, Mobile network and nothing. Any tips so I can solve this?
