Setup error on integration connection Celonis EMS <> UiPath on-premise


In a Celonis EMS action flow I am trying to setup a connection with our UiPath on-premise Orchestrator. Whatever I try I get below error. Frist I thought it were the Celonis EMS IP addresses that were blocked on the webserver, but after whitelisting those I still see the same error.

Does anybody has experience with this particular connection? Or any idea on what I could try?

Many thanks in advance!

Did you manage to get answer with it? I am also having similar issue.


Hi Nabin,

It is not working yet, only I did get some help from the Celonis support team.
On the server where you have the Orchestrator running you need to whitelist
the following IP-addresses;

    → Both inbound and outbound
    → Protocol TCL
    → Ports: 443, 5432 and 300015

Despite I did this, it is not working yet. So I asked for additional support from Celonis and out IT.

Looking forward to see if this works for you.
