FortiTester failed MITRE ATTACK breach simulation

[TDJForti]

I tried to run MITRE ATTACK breach simulation with default templates, i.e Credential Dumps, Execution thru API, etc. But all failed with error message. Confirmed that device to be tested can reach FortiTester and vice versa. I also got a firewall between them but nothing is being blocked by the firewall. Could anyone give any advice please?

Error msg:

Our practical tests with APT showed other results. And it seems FortiEDR tends more into EPP then EDR if you compare it with e.g. Crowdstrike. In any case a proof of concept should be done before selecting any EPP/EDR system for the specific business case https://routerlogin.uno/  .
