Activation / connection of Ui Robot fails

[MW23]

Hello together,

I am trying to connect UiPath Robot (I am using a Studio Enterprise trial license) to Orchestrator.

Before, with the Community Version, it worked out, going through the steps described here:

UiPath Orchestrator Tutorial | UiPath Orchestrator Guide | Edureka

However, now when I go through all the steps, finally when I want to connect the Robot i get an error:

“No connection could be made because the target computer refused the connection 104…”

Hi @MW23

Please try not to post screenshots that contain sensitive information (in this case the IP address).

Hello @MW23,
Please check if during machine deployment you have copied the correct machine key to the Robot.
Better use our official documentation:

Orchestrator - Connecting Robots to Orchestrator

This step by step process should help you

[MW23]

I think i have done everything according to the official documentation but it still gives me the same error…

[MW23]

Anyone an idea, how I can solve the issue of “No connection could be made because the target computer refused the connection [IP address]”?

(I have the latest version of Studio Enterprise installed (2019.4.3); am logged in at https://platform.uipath.com; have created a robot and used the machine key from the subsequently created machine to connect the UiPath Robot from the system tray).

In that case please open ticket in our Technical Support.

[MW23]

is that also possible with a Trial Enterprise license?
I cannot enter my company’s name and thus cannot submit the ticket:

…and i guess that is because i have entered a trial key?!

Please look that only sections with “*” are required so organization’s name is not crutial here.

Additionally please also provide License Code without any space or special characters as it stands in description.

When i try to click submit, it tells me “please fill all mandatory fields”…but the only field I have not filled is “End Organization’s Name”…but i cannot enter anything here because the field is greyed-out…

So while i cannot submit the form: would it make any sense to send an email directly to uipathsupport@uipath.com ?

with the information required in the fields…

Hi @MW23

I have found this thread which seems to be going over similar issue:

Orchestration and Machine Connection issue

Hey Mihai, It seems it’s not quite as simple as this. Here was what we think is the solution: This problem could be due to the fact that the accounts used to provision a robot (developer accounts) do not have the Local User Rights Policy ‘Access this computer from the network’ This would work when using an admin username because it will be part of the local ‘Administrators’ group which has this policy. There are 3 options to resolve this: Add the user account(s) into a group that already h…

What I could suggest is for you too make sure you have a local administrator privileges on your machine and that no firewall (including the company one) is blocking the connections between your machine and the Orchestrator CE.

Then, you can also try these two articles from our docs. This one is an official guide you should follow to provision your Robot to Orchestrator:

Orchestrator - Connecting Robots to Orchestrator

And this one is about setting up proxy for your Robot:

Robot - Redirecting Robots Through a Proxy Server

[MW23]

So the closed network was the problem, I guess.

As far as access rights are concerned: i already had admin rights - so that was not it.

But when I requested a User Guest WLAN Access where no proxy settings are used…then it worked.

Thanks for that suggestion.

PS: The link for the redirection of robots didn’t work for me:
When i went through steps 1 through 6 here (Redirecting Robots through a Proxy Server) under “Configuring the Web Browser”, then I could not reach any internet page anymore.
