I am currently studying the “2018.2 Orchestrator Training” for UiPath. While trying to connect the local robot (on my pc) to Orchestrator (tried both with and, I am encountering the error: “The remote server returned an error: (407) Proxy Authentication Required.”

I already tried the solutions proposed in Error 407 Proxy Authentication Required on UiPath Robot but with no success.

Has anyone experience in how to fix this error, or some insights on what could cause it?

Robot version: 2018.2.3
Orchestrator version: Orchestrator Community 2018.2.3

Thank you very much!
