Machine unavailable

[SA64 (Stephane Aragon)]

Hi,

I have a problem. I have two production robots installed on a virtual machine.

Orchestrator in the cloud.

All is clear but after x hours without activity, “Machine” become unavailable in Orchestrator and next process will be place in “Wait” mode.

A simple manual log on the machine wake up it.

On the machine, I have these errors every minute :

UiPath.Service.Host 22.10.7.0
submitHeartbeat: System.Net.Http.HttpRequestException: An error occurred while sending the request.

@SA64

Did you create a machine template for the vm as it is being used by teo users I beleive

You need to create machien tempalte and use machine details to connect and not interactive sign in

@SA64

Check below for your reference

Why I get this and how to avoid submitHeartbeat: System.Net.Http.HttpRequestException: An error occurred while sending the request

Dear all, I am facing the same issue. @Marcin_Bielak Could you find the solution to the problem yet? @marian.platonov Are you able to elaborate a bit why you reference this documentation to the posed issue? Thanks you!

Hope this may help you

Thanks,

Excellent ways to find the issue !

Thank you, I search in this direction and back here for news.

Unfortunately the problem is still here…

I’ve read many posts, but there is something different for me.

Error come after some hours (approx 3-4). I investigate on our system…

Hi,

Problem solved !

It was just Windows permission to uipath.com domain. My user session can access to the uipath.com domain. When I log out, Windows still access a couple of hours. But after, when no user session was open, Windows was going back to low permissions and can’t access to uipath.com.

My administrator change that and give access to uipath.com at Windows (how and where ???) and now, Orchestrator never lose the machine

Thanks for help and see you soon !
