  This is likely due to the system having IPv6 support.  Version 2.0
adds IPv6, and there are issues with binding to IPv4 and IPv6 sockets.

  Check that nothing is listening on port 1812, even for IPv6.

  Also try posting the full debug log.  Maybe there's another "listen"
section which is conflicting with the 0.0.0.0:1812.
