This may be due to the following reasons

• Proxy/Firewall in the machines may block the communication to Freshservice.

• If the asset limit is reached, new assets would reach to Trash folder within Inventory

• If the asset was already scanned and identified in a different name with a different serial number then the updates would be reflected over the existing asset. 

Reach out to our support team at support@freshservice.com for any assistance on the same.
