[Renante_Era]

Description	This article describes how to troubleshoot when the Policy & Object -> Internet Service Database number of entries is stuck at zero as shown below:
Scope	FortiGate
Solution	Confirm the internet-service database's current settings: show full system global | grep internet-service-database Update FortiGuard and confirm if that resolves the issue: diagnose debug reset diagnose debug application update -1 diagnose debug enable execute update-now Disable after around 5 minutes:  diagnose debug disable diagnose debug reset If the issue persists, try to temporarily set the internet-service database to full and rerun: 'exec update-now'. config system global     set internet-service-database full end execute update-now Undo the internet-service-database changes if the issue persists. config system global     unset internet-service-database end Note:  'set internet-service-database on-demand' is sometimes configured as a memory optimization on entry-level devices. When this option is enabled, it is expected that unused internet-service objects to contain no addresses. To update a previously unused internet-service object in this scenario, configure the Internet Service object on a firewall policy and enter the command 'execute update-ffdb-on-demand'. See the article Technical Tip: Internet-service-database: On-demand for more information on this setting. Refresh the ISDB: execute internet-service4 refresh If the device displayed an output similar to the following, then reboot the FortiGate and rerun 'exec internet-service4 refresh'. execute internet-service4 refresh Internet Service IPv4 refresh start ... Start to initialize APP file. Start to initialize MAP file. Internet Service failed to refresh. ret=-6 (shared memory error) Ensure the device has a valid support contract and connection to FortiGuard. If the device is in an HA cluster, ensure primary and secondary units have valid support contracts and are registered to the same account.
