License Validation Failures #

“Invalid License Key” Error #

Cause 1: Typo in the license key. License keys are case-sensitive.
Fix: Copy and paste the key directly from developer.dmsi.gr rather than typing it.

Cause 2: The license was already used on another domain and you have hit the activation limit.
Fix: Go to developer.dmsi.gr, find your license, and deactivate the old site’s activation to free up a slot.

Cause 3: The license key is for a different product (e.g., a DDLS Core license instead of an Analytics license).
Fix: Check developer.dmsi.gr to confirm you are using the DMSI Analytics license key, not a different product’s key.

“Could Not Connect to License Server” #

Cause: Your server cannot reach https://dmsi.gr.

Diagnosis: From your server, run:

curl -I https://dmsi.gr

Common causes:
– Server firewall blocking outbound HTTPS to external domains
– DNS resolution failure for developer.dmsi.gr
– Hosting provider blocking outbound requests (some shared hosts do this)

Fix: Contact your hosting provider to allow outbound HTTPS to developer.dmsi.gr.

License Was Active But Now Shows as Invalid #

Cause: The 24-hour license cache may be stale, or the license was deactivated remotely.

Fix:
1. Go to Analytics > Settings > License
2. Click Check License to force an immediate re-validation
3. If still invalid, log in to developer.dmsi.gr and check the license status there
