Cartes du Ciel 4 did not accept the Show Chart command

Deep-Sky Planner cannot connect with CdC4, or CdC4 did not respond as expected.

  • System security might have prevented communication. Make sure your firewall permits TCP communication between CdC4 and Deep-Sky Planner.
  • CdC4 did not understand a command sent by Deep-Sky Planner, or CdC4 understood commands sent by Deep-Sky Planner but returned an unexpected response. Be sure to run an updated version of CdC4.
  • The connection between CdC4 and Deep-Sky Planner dropped while the Show Chart command was being processed. This is highly unlikely and may indicate an unstable network connection between the two programs, a power sag or failure, or a socket communication timeout.
