Hey bradon - It looks like the camera can reach your local network, but it likely does not have working internet/DNS access to download the OTA package.
Please try updating with the download performed on your PC instead:
oakctl self-update
oakctl device info --check_internet
oakctl device update --local
The --local option downloads the update on the host and transfers it to the camera. If you use a static IP, please also check that the camera has a valid gateway and DNS server configured.
More details are here: Luxonis OS update guide and oakctl device update.
Thanks,
Oskar
