SymptomsI edited a TLD by changing a domain registrar and want to change it back to eNom, I do not see eNom in the available registrars list for this TLD.
I configured eNom certificate and domain name plans, but the subscriptions provisioning fails.
Diagnosis1. Allow the debug logging by setting ALLOW_DEBUG_LOGGING to true in /opt/plesk-billing/lib-billing/include/config/config.php.
2. Enable the debug mode (Events > Debug Log > Edit Debug Settings > Enable Debug Logging Now).
3. Choose a TLD associated with eNom (System -> System Configuration -> Domain TLDs List), and open its registrar names list.
4. Analyse the debug log (Events > Debug Log > Debug Log) for page /plesk-billing/admin/products.php and operation EditTLD. The eNom response should contain the following lines:
<err1>Invalid client IP: 22.214.171.124</err1>
