Processes suddenly started to give error

[arif_samet_ipek]

Hello,

My processes were running without any problems. The processes I run via orchestrator work normally for a while, but then suddenly give an error and stop. When I check, I encounter the error “cannot communicate with browser”. When I connect to the server remotely, I see multiple Edge tabs opened one after the other (Its because of retry, ı think.). The error occurs randomly, sometimes after 1 hour, sometimes after 5 hours. When I close all tabs and start the process again, it continues without problems for a while. Since I think something else might be triggering this error, I’m leaving here a few logs I took from the event viewer.

First,

Second,

Third,

After 20 mins from that connection issues,

lots of error logs

Is it possible that the connection ones (First three screenshots) can trigger the fourth screenshot ? Which says "UiPath.Executor 22.10.4.0
System.Runtime.InteropServices.COMException (0x80040215): Exception from HRESULT: 0x80040215
at UiPath.IUiNode.GetBrowser()
at UiPath.UIAutomationNext.Services.DriverAsyncBrowserService.WaitPageLoadAsync(IUiNodeX nodeX, Int32 timeout) "

Waiting for your help, thanks.

Please check your browser extension.

I did it, even deleted and reinstalled. Nothing changed.

Sounds like you have misconfigured your Use App/Browser activity and it’s set to open a new browser each time instead of reusing an existing browser object (which should be stored in a variable).

I assume you extension version is 22.10 based on the screenshot provided if that is the case pls refer to below link for workarounds

Edge v134 Sleeping Tabs feature affects the UiPath extensions 22.10, 23.4 and 23.10

Microsoft Edge browser update to version 134 introduced a change that affects the extension’s background page, causing automations to fail. Observed behavior After Edge browser update to version 134.0.3124.51 or higher, UI Automation activities are randomly failing for processes running on Edge.

First clear the issue of multiple broswers..by using kill before retry in exception scenario

Or check use app/browser with setting open never for where it is not beeded and open ifnotalreadyopen when needed so that multiple window issue gets resolved

Once that is done monitor the process if you still get this error

Hi @arif_samet_ipek

Are you able to upgrade your edge extension to v24.10 and try?
You will be able to find extension id from below list:

@muktadir
Thank you so much ! I was trying to solve this problem for one month… I tried everything but it didn’t work. As you said, it was caused by the sleeping tabs feature. When I turned it off, everything was fine. All 3 of my servers are working properly, again.
