Orchestrator connection error (on premise)

Hello there,

We have a problem to connect into our on-premise UiPath Orchestrator at work.

We have the following problem (coming from the Windows Event Log) :

UiPathUserServices_XXXX@xxxx 1354229 IInteractiveConnectFlow SignIn 230. # System.InvalidOperationException: Error loading discovery document: Error connecting to https://orchestrator-CERT.xxxxxx.ch/identity/.well-known/openid-configuration: Internal Server Error

Could you please help me resolve this ?

Thank you in advance.



Pls check the ssl cert got expried or recently you have updated the ssl cert then you need to update the cert’s thumb print in appsetting file

Do you have a proxy in place in the robot machine?
Did you install the robot in User Mode?
How you configured the robot in Orchestrator?
Are you using also classic folders in your Orchestrator?

Ok I found what wasn’t ok, the certificate changed and the new certificate wasn’t binded with our Orchestrator which was still on the old certificate, that’s why it wasn’t working.

Thank you all for your help.
