[tor-relays] Authdir is rejecting routers in this range

Hi all,

I rented a dedicated server to run a tor relay (100Mbit/s) to contribute to the network. On this machine, tor gives messages like these on startup:

http status 400 ("Authdir is rejecting routers in this range.") response from dirserver '<...>'. Please correct.

The server is hosted with https://fdcservers.net/.

Did I just get unlucky in picking a provider? Is there a way to check these things before spending money on setup + monthly fees?

Best regards, Davíð
