Thank you for your reply. I forgot to mention that the camera works fine when connected to a hotspot (outside the secure network). However, when connected to the secure network, it disconnects after just a few seconds. Could you clarify if the DepthAI library sends any data over the internet, or do you have any ideas on what might be causing this issue?
I tested the code with `DEPTHAI_DEBUG=1`, and the output is as follows:
DEPTHAI_BOOT_TIMEOUT=5000 python3 test.py
