  1. Check if the correct steps are performed to register DDI

    There are two ways to register DDI to Trend Micro Vision One. One is to use Deep Discovery Director On-Premises and the other one is to use Network Inventory service in Trend Micro Vision One. Trend Micro recommends using Network Inventory service to register DDI. For more details, check Enabling Trend Micro Vision One integration in Deep Discovery Inspector (DDI)

     
    In case you want to switch the registering way from using the Deep Discovery Director On-Premises to the Network Inventory service, follow steps 1 and 2 (step 3 is optional) described in Deep Discovery Inspector (DDI) and Service Gateway integration via Trend Micro Vision One.
     
  2. Check the necessary URLs and ports are allowed on your firewall rules

    For more details, check the following article and Trend Micro Vision One Online Help.

  3. Check if DDI can connect to Trend Micro Vision One using the Network Services Diagnostics

    For more detailed steps, refer to article Verifying Backend Services in Deep Discovery Inspector (DDI) 5.1/5.7

     
    Trend Micro Vision One related services should be reachable.
     
  4. Unregister and re-register DDI
     
    This step can be performed when the DDI is registered using the Network Inventory service only. If the above steps cannot solve the issue, try to unregister DDI from Trend Micro Vision One once then re-register DDI again.
