License issues

#Activation fails

• Paste the key with no leading or trailing whitespace; copy it from the purchase email.
• The host needs outbound HTTPS to validate — proxies or firewalls that intercept TLS are the usual blocker.
• Use Refresh on the Licensing page after fixing connectivity.

#Paid features stopped working

If a license expires or fails validation, paid features and connectors revert toward Free-plan behavior while your job definitions stay intact. Common causes: lapsed payment, blocked outbound HTTPS, or a key with stray whitespace. Fix the subscription or re-activate, then Refresh.

#Air-gapped or restricted hosts

• Plans tolerate a bounded offline window, so brief outages won't interrupt jobs.
• For hosts with no internet, import a signed offline license file under Settings → Licensing.

#Key never arrived

Use the activation page to look it up, or email [email protected].
