Problem with unattended robot and browser

Build

#1

When I run process from studio it works perfectly, but when I run process from orchestrator (unattended robot), browser open and web page loads inifinite. Than I connect to this machine via RDP, page immediately loaded and process continues successifully. What’s wrong with it?

Hi
welcome to uipath community
i didnt get this buddy
may i know the sequence of activities been used and the issue that you were facing

Cheers @shady2k

If process executes by orchestrator and there are no logged in user on Windows machine:

  1. Open browser UiPath.Core.Activities.OpenBrowser with specific URL
  2. Browser loading page infinitely
  3. Process throws error “Cannot find the UI element corresponding to this selector”, because page does not load

If I’m logged in via RDP when orchestrator execute this process, browser opens and page loading correctly.

@shady2k

Could you add some delay in TimeOut field of that activity and check once.

#5

Delay does not help. After process started, I’m waiting for Open Browser Executing action in log. After that I wait until job failed. Than I connect via RDP I see browser with loading page and blank screen and page immedeately load and job finishing successfully.

@shady2k

Could you try with some other web application and check once. I want to see whether the issue with this web application or something else.

#7

Different browser? IE?

#8

@shady2k

I am not talking about browser. Please check with some other web application.

#9

Ah, ok. Changed URL to another site, page still loading when I connect via RDP, but after that, loaded immediately.

#10

@shady2k

It’s weird. Then try with some other browser once and see.

#11

With IE page is loading, but it can’t find input field. Is it Chrome issue?

#12

@shady2k

May be you Developed workflow based on Chrome browser and you need to change selectors based on IE browser then only it should work.

Yes seems like issue chrome browser. Have you installed chrome extension from Uipath studio or not ?

#13

Ok, but I won’t use IE.

Yes, extension is installed.

I have the same issue but with IE. When robot is in unattended mode the page is simply not loading the full content. When starting a session manually with RDP works perfectly fine. I have added plenty of delays, doesn’t help.

I am having a similar issue running unattended bots from on premise orchestrator with IE. I have delays in the workflow however I either get could not communicate with browser or if it does open browser with a very long delay, it cant find the element that should certainly be there.

Also when I RDP to the machine I see that the bot has opened multiple windows during the workflow. However when I run it using studio on the server there is no issue.

I have a similar issue with Chrome on 2 different bots, VMs,
Bot cannot find and communicate with Browser in unattended mode.
