Might it be related to the different MAC address? Might the ISP lock service to the MAC address it sees, at least for some period of time?

Get the MAC address of your Win10 system and set the NIC of your Debian system to it, for example:
    ip link set dev eth0 address aa:bb:cc:dd:ee:ff

See if it works any better once you've cloned the MAC address.
