Common error_code values

authentication_required Session missing or invalid
rate_limit_exceeded Rate limit hit — check retry_after_seconds in metadata
fail2ban_unreachable fail2ban socket cannot be reached
config_validation_failed Config value rejected
config_file_not_found Config file does not exist
jail_not_found Jail does not exist
filter_not_found Filter does not exist
action_not_found Action does not exist
blocklist_source_not_found Blocklist source does not exist
setup_already_complete Setup has already been run

Status Code Decision Guide

Frontend gets 400 — what's wrong?

  • Has code: "invalid_input" → validation failure, check detail
  • Has code: "jail_not_found" → jail doesn't exist
  • Has code: "config_validation_failed" → config value rejected

Frontend gets 502 — what's wrong?

  • fail2ban is down or socket path wrong
  • Check code: "fail2ban_unreachable"

Frontend gets 503 — what's wrong?

  • Setup not complete (code: "setup_already_complete")
  • Health check: fail2ban offline or component degraded

Frontend gets 409 — what's wrong?

  • Already done: jail already active/inactive, setup already complete
  • Operation failed: fail2ban rejected the command
  • Conflict: resource already exists

Frontend gets 429 — what's wrong?

  • Rate limit exceeded
  • metadata.retry_after_seconds tells you how long to wait
