This article is to highlight the documentation in regards to the sync issues displayed.

Symptoms:

  • You see the following sync issues in vSphere Web Client under Networking & Security / Installation and Upgrade:
Requested URL /api/2.0/services/application/dpi/discovered-appguid could not be found. This may be caused by mismatch in NSX manager versions or missing object ID.

Environment

VMware NSX for vSphere 6.4.x

Cause

The sync issues occur because the REST API call used for the specific object exists in the upgraded Primary NSX Manager but not in the non-upgraded Secondary NSX Manager(s).

Resolution

As documented in NSX 6.4 Upgrade Guide:
If you are logged in to the vSphere Web Client during the upgrade, you will see synchronization issue warnings on the Networking and Security > Installation and Upgrade > Management page. This is because you have NSX Manager appliances with different versions of NSX. You must upgrade the secondary NSX Manager appliances before proceeding with any other part of the upgrade.

Proceed with the upgrade of the Secondary NSX Manager(s). The sync issues will be automaticall cleared after all Secondary NSX Managers are upgraded.
