ERR_CONNECTION_RESET in UiPath Cloud Robot

Hey everyone,

I’m automating a workflow using UiPath to perform lookups on the Wyoming Secretary of State’s Business Entity Search page:

:link: Business Entity Search - Wyoming Secretary of State

Here’s the issue I’m facing — and it’s specific to UiPath Cloud Robots:

:white_check_mark: Works perfectly outside UiPath

  • When I manually open the site in my local browser, everything loads normally.
  • I can input a company name, hit “Search”, and get the results immediately.
  • No errors, no CAPTCHA, no issues at all.

:cross_mark: Fails when run in UiPath Cloud Robot (Unattended Execution)

  • The bot navigates to the website successfully .
  • It enters the search term and clicks the “Search” button.
  • But then the actual search request fails with net::ERR_CONNECTION_RESET (as seen in DevTools → Network tab).
  • I opened the Live Stream from UiPath Orchestrator to investigate.

:man_detective: What I found in Live Stream (Remote Control)

  1. I took remote control of the cloud robot browser.
  2. Opened Chrome DevTools — saw the filingsearch.aspx XHR call fail with ERR_CONNECTION_RESET.
  3. Manually hit refresh (F5) in the same browser session.
  4. A CAPTCHA appeared! (which never appears in my local browser).
  5. After manually solving the CAPTCHA:
  • The site reloads correctly.
  • I enter the same search term again.
  • Click “Search” → and now the request works with no error.

:thinking: Observations

  • The issue is likely caused by bot detection or IP filtering.
  • Wyoming’s site seems to treat UiPath Cloud Robot traffic differently (perhaps due to datacenter IP ranges).
  • The ERR_CONNECTION_RESET is likely the result of a CAPTCHA or session block before the UI even presents it.
  • Once manually bypassed, the bot can function—but of course, that defeats the purpose of unattended automation.

:speech_balloon: Looking for advice on:

  • How to detect and handle CAPTCHA inside a Cloud Robot?
  • Has anyone dealt with headless browser traffic being blocked on public government sites like this?
  • Any workarounds to avoid or programmatically solve CAPTCHA in an RPA context?
  • Any advice to avoid the ERR_CONNECTION_RESET issue with no workarounds?

Thanks in advance!

I had a similar behavior.

Because my Orchestrator tenant was located in Europe, I received Access Denied errors in StudioWeb. I was able to solve after creating a United States tenant.
