I'm not surprised that it doesn't work with autonegotian if autonegotian
is disabled.
If Linux does full-duplex without autonegotiation then _they_ do it wrong
and Hetzner shouldn't rely on wrong behavour.
However since you seem to have access it might be interesting to know the
exact network device and debug why hard setting is broken.
