What Karcsham Fi errors mean and what to do next.
This is a quick reference for common Karcsham Fi messages.
No Router
Select a router from the top bar, add one under Settings > Routers, or ask a super admin for access.
Different device or Device changed
The device behind the IP does not match the saved MikroTik identity. Stop generation and publishing, open Routers, test connection, and use Re-bind only if the device swap is intentional.
Invalid host or host not allowed
Enter only an IP or hostname. Do not use http://, paths, or localhost.
Host could not be resolved
DNS failed. Check DNS or use a direct IP.
Router already exists
Edit the existing router or use a different host.
Router limit reached
Delete an unused router or upgrade from Central.
Projected Central package or Effective access denied
KF is showing the latest package projection from Central, but effective access is denied or still synchronizing. Review the subscription in KARCSHAM Central, wait briefly after a recent payment or upgrade, and send the message to support if it remains blocked.
Quarantined by subscription limit
The router exists but is outside the package allowance. Editing or re-enabling the router will not remove the quarantine. Delete an unused router or upgrade; after Central updates, the router can become operable again according to allowance rules.
Secure transport misconfigured or File transfer unavailable
API-TLS or SFTP is incomplete or failing. Check api-ssl and the RouterOS certificate, enter the API-TLS certificate name, provide SFTP username, password, and host-key fingerprint together, and keep the SFTP account separate from the API account.
Record sale/payment failed
The sale or payment could not be recorded in Voucher Lifecycle Report. Select issued unsold inventory, avoid future dates, use a valid Sale Reference for payments, do not exceed the outstanding amount, and confirm the active router.
Enter a valid report date
The report date is invalid. Use the date field and avoid incomplete or impossible dates.
