Trigger workflow through rest api from server A to B

Tries to trigger a basic workflow to test rest api trigger, gets following message:

Executor start process failed, reason System.Runtime.InteropServices.COMException (0x80070520): A specified logon session does not exist. It may already have been terminated. (Exception from HRESULT: 0x80070520)
at UiPath.UiSystemClass.OpenInteractiveWindowsSession(String bstrUser, String bstrPassword, UiOpenSessionFlags nFlags, String bstrApplication, String bstrAppArguments, Int32 nDelayMs, Int32 userToken, UiGenericOptions options)

Info:parse CompletedJson failed, ex:Object reference not set to an instance of an object. stack: at UIWorker.UIPathRobotAPI.Run(String jobJSON)

How to solved this problem?

Runnning on win server 2016, works for other servers.
