Unable to connect new Robot machine to Orchestrator

[Frincu_Ionut]

Hello everyone,

I have a problem connecting a new Robot VM to our on-prem Orchestrator using ClientID and SecretID because I am getting this error about certificate chain and I can’t find a way to solve this so far…

I already tried this but it’s not working…

The Remote Certificate Is Invalid Because Of Errors In The Certificate Chain: UntrustedRoot

When trying to connect the Robot to Orchestrator via the machine key option, the below error is encountered: "RemoteException wrapping System.Security.Authentication.AuthenticationException: The remote certificate is invalid because of errors in the certificate chain: UntrustedRoot" Most likely, Orchestrator is using a self signed certificate and this certificate must be imported to the Robot machine as well. Usually, the error encountered in the Assistant when connecting the Robot to Orchestrat…

Error log about this:

Do you have any idea how to solve this? Thank you!

Hi @Frincu_Ionut

Please check below thread

Unable to license cloud robot - Error: The remote certificate is invalid because of errors in the certificate chain: PartialChain

Try to download the Orchestrator certificate and add the certificate to the trusted root certificate of the robot machine. Also, as last resort, after you installed the Orchestrator certificate in the robot machine, you may try to uninstall completely the robot from the impacted machine (for this follow this documentation Studio - Modify or Uninstall Studio) → restart the machine → reinstall again, and then retry the connection to Orchestrator. References: Let us know if this helped.

Hello @lrtetala , I already tried this, but unfortunately it’s still not working…

What is the Orchestrator URL used in UiPath Assistant?

Hello @marian.platonov, the URL is a normal one, and I already connected some other machines to it, and I want to find out why this one is not working and how to solve this…

From a working machine, extract the url certificates from the browser. Then add them in your machine under the trusted root. Then retry the sign in.
