- "License key not found" – You typed it incorrectly or the key is for a different product (e.g., Kerio Connect, not Control).
- "License expired" – Time to renew your subscription.
- "Maximum user count exceeded" – You have more active IPs than your license allows. Either buy a larger license or use DHCP to limit connections.
