Accessing client device connected to Android phone via Ethernet Tethering

I have an Android phone which I can share its internet connection via Ethernet tethering through an adapter (Ethernet to USB-C adapter). The device (camera) which is connected to the phone is able to utilise the internet connection successfully. I want to access the device from my Android phone using its local IP address in the web browser of my Android phone since that device (camera) has a webapp running on it which allows accessing its features and configurations. However when I type in the local IP address (or the local host name) of the device in the browser it times out (the IP address is correct and I have double checked this multiple ways). 1. is this possible on Android? 2. how can I achieve this? 3. is this a DNS problem? (my Android "Private DNS Mode" is set to "Automatic" which is the default option. I can achieve this using a laptop running windows without any issues but being able to use a mobile phone is a lot more convenient, as it means I won't have to carry a laptop with me.
