Timeout reached. UiPath.UiAutomation.Activities

I have a process that has been running ok for several years unattended. all of sudden it throws this error at multiple uielement activities throughout, when I run it attended everything works, can someone please tell me why? it threw this error before the timeout was reached too.

Thanks, it’s so strange, I have check app state everywhere…and this doesn’t happen when running attended.

Yeah..

Is it happening for a particular activity or all?

If it’s for all, there may be temporary slowness in application today thus leading to timeouts.

Hi @Lynn_Song

Please check the selectors and fine tune, might be something changed.
Or you can also check the screen resolution.

Happy Automation

Hey @Lynn_Song can you show us the logs to detect which particular activity you are getting error.because there are multiple possibilities for these error.
eq- window resolution , selector issue, might be you have to use element exist or Retry activity , maximize window, wait for ready - should be complete, screen resolution might be changed .

cheers
