Unable to download DNSWL via rsync

[Joe Muller <joe.muller@xxxxxxxxx>]

   I work for an ISP (Sonic.) that utilizes the DNSWL dataset as part 
of our spam filtering. We have two servers running rbldnsd which are 
configured to download the DNSWL data via rsync. Starting on 20220712, 
our download script stopped downloading new data. I'm seeing the 
following error:

# rsync --ipv4 -vvv --times --exclude 'acl*' 
rsync2.dnswl.org::dnswl/rbldnsd-* /var/lib/rbldnsd/data/
opening tcp connection to rsync2.dnswl.org port 873
Connected to rsync2.dnswl.org (142.44.243.216)
sending daemon args: --server --sender -vvvte.LsfxC . "dnswl/rbldnsd-*"  
(5 args)
rsync: read error: Connection reset by peer (104)
rsync error: error in socket IO (code 10) at io.c(792) [Receiver=3.1.2]
[Receiver] _exit_cleanup(code=10, file=io.c, line=792): about to call 
exit(10)

   Our subscription shows as current on the dnswl.org website, so I'm 
confused why downloads are not working. Can someone from the team please 
reach out to me?
