One thing in addition. It might happen that Rtorrent will fail as well with following error message.
May 08 14:52:46 DietPiVM1 rtorrent[530]: rtorrent: Error in option file: ~/.rtorrent.rc:49: Invalid argument.
but this is quite easy to fix. You could follow this user guide (but might have different settings)

Or you simply going to change DHT mode on /mnt/dietpi_userdata/rtorrent/.rtorrent.rc from dht.mode.set = enabled to dht.mode.set = auto

probably something to adjust on our default config for Buster based systems.
