Orchestrator issues


When I try to connect to the demo Orchestrator I’m getting this error message:

“Authentication failed because the remote party has closed the transport stream”

Any idea about what is happening?

Thank you.

Hey @Pablo

The webservice you are calling may be it does not support TLS 1.0 they supported 1.1 and 1.2. So I had to change the security protocol.
Another option is add the following Registry key:

Key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 
Value: SchUseStrongCrypto 

It is worth noting that .NET 4.6 will use the correct protocol by default and does not require above solution.

Best Regards…!!

I try that, thank you very much! :slight_smile:


I changed the registry key but the problem still exists…

For more explanation, I just tried to connect the uirobot to the Demo Orchestrator, it wasn’t a job launch…I entered the hash key of asigned to my computer and the http://demo.uipath.com in the config popup of uirobot, and it showed a popup of error with that message after half a minute…

Any ideas would be welcome…thank you very much

Hi again

It seems the problem is an update of .Net Framework, KB4019108. It fixes some issues about SH1. SSH/TLS, and at least in my case after uninstalling it the uirobot connected with the orchestrator

Kind of weird…
