I have an OAK-D Pro PoE and I just did the bootloader Update Bootloader version 0.0.24
Any idea why is this happening?

Hi RafaelRodriguez
With debug disabled, the script works?
Also what command are you using to enable the debug mode?
Thanks,
Jaka

Sorry for the late response; this issue was solved by changing my router (not enough processing power)
