UiPath Subscribe timed out at opening project

Hello everyone! Currently I have installed UiPath Studio 2021.10.3 (Community) and when I am trying to open any project or the Studio itself, I get an error message “Subscribe timed out”.

Here is the full message of the error:

21.10.3+Branch.master.Sha.8291b2799a85589c5b075e0d1f69016fc83eec97

Subscribe timed out.

I have tried to uninstall and reinstall UiPath, it works fine for a few hours, but the next day the same problem occurs.

Can anyone help me with this issue? Thank you!

Hi! welcome to community!

Restart your pc/laptop once!

Thank you for your quick response! Unfortunately I have tried that several of times but the issue is not solved :pensive:

@alina.boarca please use the Diagnostic Tool to export some logs and share them with us. We will investigate and try to provide a fix/workaround.

Thanks,
Alexandru

Hello @alina.boarca! Please try uninstalling UiPath Studio and delete all traces of UiPath products: the ones in %localappdata% included and %appdata%. After that try to make a fresh install with the 2021.10 installer. That worked before, I hope it will work for you as well!

Hello @AlinaCapota , i’m having the same issue as @alina.boarca. I tried uninstalling and deleting all the files and reinstalling but it is the same issue. When launching it’s giving “Subscribe timed out” and the same errors.
