Hi there @lawanyaram.
It sounds like your connection might be blocked by a firewall or group policy or otherwise impeded.
Back when the last Excel pack was released @Mr_JDavey answered something which seems identical to your issue, here, so lets use the same approach.
m attaching a .zip file with the new Excel Activity, which you need to unpack in your local UiPath installation paths Activities folder.
That is to say something along the lines of: “C:\Users\ciprian\AppData\Local\UiPath\Activities” (like in my case).
You can also try to find the folder in question by pasting: %localappdata%\UiPath\Activities in your Windows Explorer address bar.
Please be mindful to the fact that the installation location might be different depending on your version.
